Polyester Rope vs Nylon Rope: The Differences You Need to Know

Introduction

Are you finding that picking ropes is easier said than done? You see, choosing the right rope is a matter of safety, and some ropes stretch under heavy loads while others remain rigid. It does not matter if it is a polyester rope vs nylon rope; the goal is to find a rope that matches your use case. This guide has everything you need to know.

Nylon Rope – Why It’s on The Hype?

You have probably heard about nylon rope, since it is one of those components that gets a lot of attention. A nylon rope is a synthetic rope that has very high strength, in fact, it is made from woven nylon fibers, which results in the great elasticity nylon ropes are famous for. It has strong shock absorption and a high level of tensile strength. For instance, what is nylon rope used for?

People use it in climbing and vehicle rescue, which is why the nylon rope strength is so sought after. Almost every polyester rope vs nylon rope debate has the same winner: nylon. It wins because of its perfect performance in dynamic scenarios. What is a nylon rope? It is a reliable tool. The nylon rope definition points to its polyamide fiber origin, and the nylon rope manufacturing process creates its unique properties. For those asking what is nylon rope made of, it is a polymer.

Polyester Rope – What Makes It Unique?

Have you ever heard of polyester rope? You might also hear people call it Dacron or Trevira. It is a type of synthetic rope made of polyester fibers. This rope is often called an all-purpose rope. You will find it has high strength and low extensibility. For example, a common question is, is polyester rope waterproof?

It has a very low water absorption of under 1%. In the polyester rope vs nylon rope debate, polyester is the clear winner for outdoor use. Its melting point is about 255°C, and this makes it great for high-friction jobs. The polyester rope definition highlights its durability. You can often buy polyester rope for many tasks.

Polyester Rope Vs Nylon Rope: A Core Technical Comparison!

A.    Decoding Tensile Strength & Breaking Loads

In this section, you will learn about the basic strength differences of these two well-known ropes. We will also see their holding ability in different situations. Understanding rope types and strength is key, in addition to the rope strength comparison between a polyester rope vs nylon rope.

1.       Nylon’s Raw Power

One of the biggest features of nylon rope is the strength it holds, even with sudden loads. This section outlines its major power advantages. Quality nylon ropes are known for this.

Higher Tenacity

You see, more powerful ropes can hold more individual strands; thus, nylon ropes have greater tethering power. For instance, polyamide rope fibers have a tenacity of 45-80 MPa. This sheer nylon power is why it is often preferred over polyester ropes in the great polyester rope vs nylon rope discussion.

1500 kgf

The breaking strength of a nylon rope 6mm with a 12-strand braid is 1200-1500 kgf (12.0-15.0 kN). Let me tell you, a nylon rope 16mm is incredibly powerful for even the most challenging tasks. You can find many nylon rope sizes, including nylon rope 2mm, nylon rope 3mm, nylon rope 5mm, and nylon rope 10mm from a nylon rope wholesale supplier.

Dynamic Superiority

Nylon features superior nylon climbing ropes to polyester, because it can absorb sudden forces and energy. This is the biggest deal-breaker in the nylon vs polyester climbing rope case. Fall protection is the first line of defense, and this is especially true during rappelling and rescue. It can keep people and objects from falling. This is why mountain climbers use nylon ropes and why nylon is used for making rock climbing ropes. Are climbing ropes made of nylon? Yes, for this reason. Many wonder why are nylon ropes used in rock climbing, and the answer is safety. It helps to explain why nylon ropes are used in rock climbing.

2.       Polyester’s Static Might

You will find that static tasks are performed with polyester rope because of its sturdiness and consistency. Polyester ropes offer great resistance to stretch and environmental factors, which is a major point in the polyester rope vs nylon rope conversation.

1300 kgf

A 6mm, 12-strand, braided polyester rope has a breaking strength between 1,000 to 1,300 kilograms of force. This is equal to 10.0 to 13.0 kN. Although a bit lower than nylon, it is still impressive. For many tasks, a polyester rope 14 size delivers dependable static strength. The polyester rope price is also a consideration.

Load Stability

As a result of its low stretch, a polyester rope for swing use is the best option. Superior load stability is maintained, and this means it does not change length under tension. Stability is crucial for a polyester flag pole rope or lifting equipment.

Consistent Strength

The dependable strength of marine grade polyester rope is maintained in both dry and wet conditions. Because polyester rope has the least water absorption, it is more dependable for marine lifting operations than nylon rope. Therefore, the 3 strand polyester rope is highly dependable. A polyester robe is different from a rope.

3.       Weave Structure Impact

The way a rope is woven has its own set of rules influencing its grappling and strength. Performance is greatly enhanced by understanding the different styles of weaving in the polyester rope vs nylon rope choice.

Kernmantle Strongest

A low stretch kernmantle rope has the highest strength of all types. Kern rope has a core, the kern, which supplies the strength. The sheath, or mantle, surrounds it and acts as a protective barrier. This construction supports lifesaving purposes, and it ensures the user has the highest level of security and durability.

Double-Braided

A double braid polyester rope, such as a 10mm double braid polyester rope, has a braided core and a braided cover, making it one of the strongest and most flexible constructions. Hence, a 1/2 inch double braided polyester rope is easily manageable. It strikes a perfect combination of strength and wear resistance, making it ideal for many tasks, like with a 12mm double braid polyester rope or 3/16 double braid polyester rope. A double braided polyester rope is very reliable.

3-Strand Twisted

A 3 strand twisted polyester rope is easy and inexpensive to splice. It is a common, though lower strength, rope construction. The 3 strand polyester rope 14mm has a low break strength compared to other weaves, making it ideal for general outdoor tasks. The three strand polyester rope is a classic choice. A 3 stranded rope is quite common.

B.     Analyzing Elasticity & Shock Absorption

Elasticity is the most important factor in determining the vertical impact forces on a moving rope. This section assesses the ability to absorb shock in the polyester rope vs nylon rope comparison.

1.       Nylon’s High Elongation

Nylon rope is the synthetic rope with the most elasticity. It is designed for stretch ropes and other high-impact jobs. The Hercules tow ropes nylon rope is a good example.

Up To 30%

You might ask, does nylon rope stretch? Yes, it does. It stretches up to an impressive 30% while maintaining its elastic recoil properties. 30% of the rope’s length also serves as ‘rest length’. The nylon rope exhibits behaviors like a rubber band. This ‘dynamic stretch’ is shown on a nylon rope stretch chart. This is the most praised stretch performance in the polyester vs nylon rope stretch debate.

Absorbs Energy

Due to its high elongation, nylon rope absorbs more than 2.5 times the shock energy of polyester ropes. This is a great advantage for a rope, as it lessens the impact of a sudden dynamic change. Consequently, it protects the load. This is why are nylon ropes which stretch considerably are used for towing. You might wonder how does nylon ropes affect impulse momentum, and this is the key. It is the same for how does nylon ropes effect impulse momentum.

Dynamic Scenarios

In dynamic scenarios, the tension on the rope protects equipment and people from sudden jerks. For this purpose, high-quality nylon ropes are the most suitable. Such rope can be used for vehicle rescue, climbing, and fall protection. This answers the question, ‘why are climbing ropes made of nylon?’. You can even find a nylon rope book on the topic. The debate of nylon vs polyester rescue rope often favors nylon here.

2.       Polyester’s Low Stretch

On the other hand, polyester’s low stretch increases stability and control when used in static positions. It is the most preferred rope in applications that require it to be firmly static.

<15% Elongation

Does polyester rope stretch? Not much. Its 15% elongation means it has low elasticity and high extensity. Thus, it is not suitable for dynamic shock but is excellent for static use. The polyester rope vs nylon rope debate usually hinges on this key difference.

Maintains Stability

Under tension, a solid braid polyester rope keeps its length. This allows the rope to be used on flagpoles, in tents, for heavy-duty lifting, and more. Many buy polyester rope for its reliable tension, high sag resistance, and diminished elongation over time.

Static Rigging

For static use, a twisted polyester rope is more appropriate. The low stretch of the rope allows for control and securing of loads. This is a perfect fit for industrial rigging, secured cargo, and more, where movement is a safety concern. It is also great for a strong black cord. In the nylon vs polyester static rope comparison, polyester is the winner.

3.       Energy Absorption Rate

The energy absorption of a rope is a safety consideration that must not be overlooked. It heavily determines how much energy is lost during a sudden impact.

Nylon 2.5x

Nylon ropes can absorb, on average, 2.5 times more energy than any rope made of polyester of the same size. In any nylon rope experiment, this element stands out. This is a useful component of the rope, necessary to ensure the safety of people and protect machines from dynamic shocks.

Reduces Peak-Loads

The 1 4 solid braid nylon rope, due to its high elasticity, is able to lessen the peak loads on the rope and anchoring points. For example, in mooring, the rope absorbs impacts from surges and tides, protecting the vessel and hardware from damage.

Crucial Safety-Factor

Many applications rely on this type of nylon line for safety. This is one reason mountain climbers to use nylon ropes. It absorbs shock, so the climber can feel more secure. The Marlow ropes brand is well-known for this. In terms of impulse and momentum why are nylon ropes so effective? It is because of this shock absorption.

C.     Evaluating Performance In Wet Conditions

Damp conditions can greatly affect rope performance. In this segment, we will compare wet conditions for both nylon and polyester ropes in the context of polyester rope vs nylon rope.

1.       Nylon’s Water Absorption

The performance of nylon changes in wet conditions because it tends to absorb water.

10% Absorption

Nylon marine ropes have a water absorption rate of around 4-10%. This causes the fibers to swell and soften when wet, which changes the rope’s properties. This is one of the main nylon rope disadvantages.

Loses 15% Strength

A white nylon rope can lose 10-15% of its strength when wet. This can pose a safety risk. This is a key factor when considering hemp vs nylon.

Becomes Heavier

Water absorption is the main reason that nylon mooring ropes UK become difficult to handle. For marine applications, specially treated nylon is available but is pricier. This also influences the rope prices.

2.       Polyester’s Hydrophobia

Polyester rope is almost wholly waterproof, providing a reliable option in marine and wet environments, as it does not lose its core properties. This is a key point in the polyester rope vs nylon rope comparison.

<1% Absorption

The absorption for a 100 polyester rope is very low, at less than 1%. This means it remains practically unchanged in wet and dry conditions. This is important in the polyester rope vs polypropylene rope discussion for marine use.

Retains 98% Strength

Even when wet, polyester retains 98 to 100% of its strength. This means it performs consistently and is more dependable than nylon. For this reason, a heavy duty polyester rope is ideal for mooring lines and polyester vs nylon anchor rope choices.

Stays Lightweight

A polyester fishing line also remains lightweight and easy to handle, even when submerged. Its lack of water absorption means a constant weight is easy to work with, which lessens strain on equipment. This is true for many types of cordage.

3.       Wet Abrasion Resistance

The combination of water and friction is a rope’s ruggedness test. Abrasion resistance is how a rope resists wear, which is key for its longevity, especially in a polyester rope vs nylon rope showdown.

Nylon Softens

Like other braided nylon ropes, nylon rope softens when wet. This increases filament surface friction, and therefore, abrasion resistance is diminished. This renders it ineffective for high-friction applications in the wet. A strong white rope, for example, can wear out quickly when misused.

Polyester Stable

On the other hand, polyester ropes remain stable in terms of abrasion resistance in both dry and wet forms. Their fibers do not soften, which makes them far better for marine applications. A Dacron polyester rope, for example, is commonly used for mooring lines and buoy ropes.

Superior Marine-Use

Because of its stability in wet and high-friction situations, polyester is the best for marine applications. In the polypropylene vs nylon anchor rope debate, polyester is often the common choice for its proven performance in rough marine conditions, which guarantees a long service life and improved safety.

D.    Breaking Down Environmental Resistance

The ability of a rope to withstand sun, heat, and chemicals directly affects its longevity. This section covers these resistance properties for polyester rope vs nylon rope.

1.       Ultraviolet (UV) Durability

The strength and lifespan of rope fibers can decline as they are exposed to sunlight. When ropes are out in the sun, the ability to survive UV rays is crucial.

Polyester Superior

You might ask, is polyester rope uv resistant? Yes, it is more UV resistant than nylon and retains its structure and strength after prolonged outdoor exposure. This makes it a better choice in the polyester vs nylon rope UV debate.

5-Year Lifespan

With its UV resistance, a 1 inch polyester rope can last up to 3 to 5 years outdoors, while its nylon equivalent lasts only 1 to 2 years. This makes polyester more cost-effective over time.

Nylon Becomes-Brittle

Nylon tends to age much quicker under direct sunlight. UV exposure causes the polyamide rope fibers to become hard and brittle, losing strength. This degradation makes it unsuitable for prolonged sun exposure. You can find this kind of rope on indiamart.

2.       High Thermal Tolerance

Heat from friction or the environment can weaken a rope, which is an undesirable trait.

Polyester 255°C

Polyester and nylon rope have different temperature tolerances. Polyester can withstand a temperature of 255°C and retains most of its strength up to 150°C. This makes it a better rope for high-temperature and friction applications.

Nylon 210°C

Finding the melting point of a nylon plastic rope means it can no longer be nylon, as it has a melting point of approximately 210°C. Its strength starts to decline closer to 100°C. At higher temperatures, it softens and ages quicker, which is why its optimal use is at room temperature.

Resists Friction-Heat

Also, a black polyester rope, is used for winches and pulleys since any heat created by friction is less damaging. It is made of polymer polyester, which is stronger and more resistant to friction heat, making it less prone to breakage. The same applies to a red poly rope.

3.       Chemical Resilience Profile

In industrial or marine applications, ropes come into contact with various chemicals. Resistance to acid, alkali, and oil is essential. This is a critical factor in the polyester rope vs nylon rope choice.

Polyester Acid-Resistant

What is one of polyester rope’s strengths? It offers better corrosion resistance to acid, oil, and other destructive agents. This resilience differentiates polyester rope from nylon rope and also makes it a better alternative than polypropylene rope.

Nylon Alkali-Resistant

While weak against acid, a nylon rope 2mm or nylon rope 3mm thick can withstand a majority of alkaline substances, as well as oil. This makes it useful in specific industries. However, long exposure should be avoided. A nylon rope 5mm variant is also available.

Industrial Settings

Because of their differing abilities to withstand corrosion, these ropes are suited to specific industrial settings. For example, polyester is used in corrosion-resistant applications, such as industrial ropes and buoy lines. This also applies to pp pe nylon ropes.

E.     Comparing Abrasion & Wear Characteristics

A rope’s ability to withstand frictional rubbing and other opposing forces is its abrasion resistance. This is an important aspect of a rope’s overall longevity. The nylon vs polyester rope durability is a key topic.

1.       Polyester’s Superior Toughness

Polyester is durable and wear-resistant, which justifies its use in high-friction applications. The 12 polyester rope is a great example.

25% Better

In summary, a 1/2 polyester rope will offer 15-25% better abrasion resistance than a nylon rope. This makes it more favorable in conditions where high friction is sustained over a long period, improving the longevity of the rope. This is a clear advantage in the polyester vs nylon rope strength debate.

High-Friction Use

A durable 3 8 polyester rope is no match for repeated friction. This is ideal for mooring lines, rigging, and winch lines, where its strength is not affected by wear and tear over time.

Longer Service-Life

The abrasion resistance of a 1 4 polyester rope leads to lower replacement frequencies. This increases its long-term cost-effectiveness, making it a better value over time for demanding tasks. This is also true for the polyester hammock rope and hammock polyester rope.

2.       Nylon’s Smooth Surface

The smooth abrasion resistance nylon offers in dry conditions changes when wet. The nylon rope yellow is an example.

Reduces Friction

When dry, the surfaces of a colored nylon rope and rope string-like nets bend and pull without catching. This translates to good abrasion resistance and low wear, which is critical for use in towing ropes and climbing nets. The nylon rope HSN code is also useful here.

Excellent Dry

Nylon ranch ropes deliver optimal performance in dry conditions. Surface friction is effortlessly handled when the rope is dry. This is a huge advantage for ranchers but a disadvantage when the ranch is wet. This is a critical point in the poly vs nylon ranch ropes conversation.

Reduced When-Wet

When wet, nylon rope softens and loses abrasion resistance. For this reason, it does not meet the needs of wet, high-friction scenarios. In the cotton vs nylon ropes comparison, nylon is stronger, but both share the weakness of water regarding abrasion. Ebay nylon rope is a place to find it.

3.       Fiber Hardness & Durability

The inherent strength of a fiber contributes to the overall toughness of the rope and its resistance to fraying.

Polyester Harder

The fibers in double braid polyester ropes undergo a more rigorous process than those in nylon ropes. Because of this, they are more resistant to abrasion. A 10mm double braid polyester rope heavy duty is a great contender for sturdy tasks.

Resists Fraying

The 1/2 inch polyester rope is made of stiffer braided fabrics, making it more resistant to fraying. This is especially true for rigging and mooring lines. The added structural integrity helps prolong its life.

Nylon Softer

Nylon ropes, especially the braided poly rope types, retain high elasticity and softness. Because of this, they are easier to manage and knot. On the other hand, being softer means, it is more prone to abrasion, especially when wet. You can find it at nylon rope lowes. A nylon rope thin is very flexible.

F.      Unpacking Physical & Material Properties

The elasticity, density, and knot stability determine how a rope performs and is used. These traits are key when determining a rope’s effectiveness and purpose, especially in the polyester rope vs nylon rope analysis.

1.       Specific Gravity & Density

Specific gravity determines a rope’s ability to float or sink. This is very important for marine ropes, so it is crucial when determining its use.

Polyester 1.38

The specific gravity of a diamond braid polyester rope is 1.38 g/cm³. Because of its negative buoyancy, it sinks under water. Polyester rope is relatively dense, so it is useful for anchor line applications that require the rope to remain submerged.

Nylon 1.14

The specific gravity of a 3 16 nylon rope is 1.14 g/cm³. Just like polyester, it is also denser than water, which means it will sink. This is an important factor in the nylon vs polyester vs polypropylene rope comparison because polypropylene rope floats.

Both Sink

Does polyester rope float? No, neither polyester ropes nor nylon ropes float. Both materials have a specific gravity greater than 1.0, so they sink. This is why they cannot be used for buoyant applications like rescues or pool markers.

2.       Knot Performance & Stability

The more a rope can hold a knot without slipping, the more secure and safer it is. The material, surface, hardness, and structure all play an important role.

Nylon Easier-To-Knot

Nylon ropes are softer and more elastic, which makes them easier to knot. Its smooth and flexible structure makes it easy to tie. Projects like DIY decorative knots and nylon rope book applications benefit from such softness. That is why many people get it from nylon rope Michaels.

Polyester Holds-Better

A braided poly rope is harder but retains knots more efficiently. Knots are more secure and stable, making them less likely to come undone under load, which is a major safety advantage. This makes it the best rope for outdoor swing applications.

Less Knot-Slippage

The smoother surface of nylon can result in knot slips. Polyester is easier to knot and untie and also tends to slip less, which makes it more reliable. This is why it is often used for load-securing applications, making it ideal for a 34 nylon rope.

3.       Fiber Memory & Creep

Creep is the permanent deformation of a rope under a constant load, while fiber memory is the tendency of a rope to return to its original shape after being stretched. This is a defining factor in the polyester rope vs nylon rope choice.

Nylon Recovers-Shape

Stretching nylon leads to elastic deformation, and once the load is lifted, the fabric goes back to its original shape. This is why nylon ropes are used to aid in rock climbing. Any sudden vertical descent is absorbed by these ropes, saving a climber from a fall.

Polyester Resists-Creep

A 12 strand polyester rope shows excellent resistance to creep, holding its length and shape under tension. Over time, the rope shows almost no permanent deformation, making it perfect for static applications like rigging and guy lines. Its use for polyester flagpole rope is also justified.

Minimal Deformation

A 2 inch polyester rope or 2 polyester rope shows minimal deformation because it resists creep so well under load for a long period. This maintains the rope’s stability, reliability, and consistency, which is highly valuable in the industrial and marine sectors.

G.    Understanding Safety & Failure Modes

Safety is critical, especially how a rope behaves when it breaks. Recoil and fatigue resistance are indispensable factors for understanding a moving rope’s safety.

1.       Recoil & Snapback Risk

When tension is released from a breaking rope, stored energy is released, causing the rope to snap back and potentially damage people or equipment. This is a key safety point in the polyester rope vs nylon rope comparison.

Nylon High-Recoil

Nylon elastic fabrics hold huge amounts of energy under load. Thus, if a nylon rope with wire core breaks, this energy is released suddenly, resulting in a powerfully high recoil snapback, which is a significant safety risk.

Polyester Low-Recoil

On a dunnage sheet, a 3 4 polyester rope has very low elasticity and low snapback recoil. This type of rope, when cut under tension, stores less energy than nylon, and its snapback is remarkably lower. This low snapback makes it a more favorable option for static applications and is a key point in the nylon vs polyester rope durability debate.

Safer Breakage

Polyester’s low recoil makes for a calmer breakage mode. The reduced snapback greatly lessens the risk of injury or damage when the rope fails, which is why it is the more favorable option for lifting, rigging, and other static uses that rely on safety. It also has great use in polyester rope NZ.

2.       Tensile Fatigue Resistance

Tensile fatigue is the weakening of a rope from repeated loading and unloading. High resistance to this results in a longer, more reliable service life.

Polyester High-Resistance

A 5 8 polyester rope has high resistance to tensile fatigue and retains its strength well under repeated loading. This durability makes it a reliable choice for applications with cyclical loads, including mooring lines and rigging systems.

Nylon Exceptional

Nylon battle ropes exhibit exceptional fatigue resistance and endurance. This makes them well-suited for dynamic applications. For climbing and fall protection, the choice between polyester vs nylon rescue rope is often scenario-dependent.

Repeated Loading

How well both materials perform under repeated loading is where their applications differ. How does nylon ropes affect impulse momentum? They are widely used for dynamic purposes. Polyester is more stable for static cyclic loads. The rope strength comparison also depends on the type of load being applied.

3.       Common Signs Of Wear

Knowing and being able to identify the signs of wear and tear of a rope is very important for its safe use. Retiring a rope is the last resort. With the right use and regular inspections, accidents can be prevented.

Nylon Hardens

With prolonged use, 34 braided polyester lines that feature nylon will start hardening and becoming brittle, especially with UV exposure. The ropes will lose their flexibility. The more flexibility a rope loses, the more it shows its age and should be disposed of.

Polyester Fuzzes

A 12mm polyester rope or 10mm polyester rope will wear out and its skin surface will become softer than the rest. Rough surfaces start showing signs of wear. The outer parts of the rope are worn the most by friction. It is a softer damage than hardening, but considerable fuzzing should send the rope for further examination. This is super useful for outdoor polyester hammocks rope.

Regular Visual-Inspections

Both types of ropes require regular visual inspections. Hardening, fuzzing, cuts, and worn areas need to be monitored before every use. It saves the rope and makes it usable constantly, especially for ropes exposed to UV rays.

Why Choose Polyester For Static And Marine Applications?

When it comes to the most challenging jobs, polyester remains unbeatable because of its unmatched characteristics in ensuring stability, longevity, and safety. The polyester rope vs nylon rope choice is clear here.

Low Stretch

An example would be the elongation of a 3 4 double braided polyester rope. Its elongation is very marginal, which gives stability in static rigging and mooring. It eliminates sagging and keeps a fixed tension on the rope. Hence, loads are secured, and vessels are moored in a guaranteed position. This is one reason why polyester rope is preferred over polypropylene rope and nylon rope.

Maintains Stability

The low elongation a 4mm polyester rope or a 5 16 polyester rope has is perfect for conditions that require support. This works wonderfully for industrial lifts that require high precision and for a polyester rope hammock where sagging is not an option.

Excellent UV-Resistance

For any polyester rope for outdoor use, the UV resistance is amazing. It can undergo years of direct sunlight without big signs of deterioration. This goes for the 3 16 polyester rope and 3mm polyester rope, constructed for outdoor purposes like assisting polyester flagpole rope or supporting climbing plants with polyester vs nylon rope for garden trellises. The marine grade polyester rope UV resistance is also top-notch.

98% Wet-Strength

A 1/8 polyester rope still retains almost all of its strength when fully saturated, unlike nylon rope. Its hydrophobic fibers absorb less than 1% water, and as a consequence, it retains 98% of its dry breaking strength. Marine grade polyester rope works well even when wet.

Corrosion Immunity

Polyester ropes are immune to rot and mildew. They are resistant to acids and other corrosive substances. This means a 2mm polyester rope can be used in extreme marine and industrial conditions, guaranteeing a prolonged and dependable service life.

Static Rigging

Due to its combination of low stretch, high strength, and durability, a polyester nylon plastic rope is used for static rigging. For instance, a 12mm double braid polyester rope is ideal, as it provides the stability and reliability needed to secure and support loads and structures.

Characteristic	Polyester Rope	Nylon Rope
Breaking Strength (6mm)	1,000–1,300 kgf	1,200–1,500 kgf
Elongation at Break	10%–15% (Low Stretch)	20%–40% (High Stretch)
Abrasion Resistance	Excellent (15-25% better)	Good (Reduced when wet)
Water Absorption	<1% (Hydrophobic)	4%–10% (Hydrophilic)
Strength When Wet	Retains 98%–100%	Loses 10%–15%
UV Resistance	Excellent	Good (Degrades over time)
Melting Point	~255°C (491°F)	~210°C (410°F)
Specific Gravity	1.38 (Sinks)	1.14 (Sinks)
