Ultra-high-molecular-weight polyethylene filament fabric for bulletproof vests and high-performance conveyor belts

Ultra-high-molecular-weight polyethylene filament fabric is made by weaving filaments together.

Common specifications for UHMWPE filaments include 200D, 400D, 600D, 1000D, and more. They typically feature properties such as cut resistance, puncture resistance, and impact resistance.

Characteristics of ultra-high-molecular-weight polyethylene:

1. Mechanical Properties: UHMWPE fibers exhibit exceptionally high specific strength (the ratio of strength to density) and specific modulus (the ratio of modulus to density), meaning they can deliver remarkable strength and resistance to deformation while remaining remarkably lightweight. The tensile strength of these fibers typically ranges from 25 to 45 cN/dtex.

2. Excellent cut resistance and abrasion resistance: This makes it indispensable in the field of safety protection.

3. Low Density: With a density lower than 1 (lighter than water), the material is lightweight and produces fabrics that are soft, comfortable, and place minimal strain on the wearer.

4. Excellent chemical stability: Outstanding resistance to chemical corrosion (insoluble in any solvent under normal conditions) and capable of withstanding low temperatures.

5. Other excellent features: It also boasts advantages such as impact resistance, UV protection, self-lubrication, and excellent water permeability and breathability.

The core application of UHMWPE filament fabrics always revolves around their inherently "lightweight yet strong" properties. When selecting these materials, it’s essential to focus on their key performance characteristics based on the specific scenario at hand.

Bulletproof and stab-resistant: Opt for unidirectional (UD) fabric or fabrics with a specific woven structure, paying attention to their density and protection level.

Cut-resistant: Choose high-density woven or knitted fabrics, and pay attention to the cut-resistant rating.

Ropes and Cables: Focus on fineness, strand strength, and abrasion resistance.

Wear-resistant lining: Focus on the wear resistance index and impact resistance.

Applications of ultra-high-molecular-weight polyethylene:

1. Security Protection Field

This is one of the most common application areas for UHMWPE. One, primarily used for manufacturing life-critical protective equipment. Equipment.

Bulletproof and stab-resistant gear : Used to manufacture bulletproof vests, bulletproof helmets, stab-resistant garments, and cover fabrics for ballistic plates, among other products. Its high specific strength effectively absorbs and disperses the kinetic energy of bullets or sharp objects upon impact.

Cut-resistant gloves and apparel : Applied in industries such as meat processing, glass manufacturing, and metalworking, it protects workers from cuts. Its cut-resistant performance far surpasses that of ordinary fibers.

High-performance safety shoes : A cut-resistant layer used on the shoe upper, protecting the feet from injuries caused by falling sharp objects.

2. Marine Fisheries and Shipping Sector

Due to its resistance to seawater corrosion, high strength, low density (allowing it to float), and UV resistance, it has become an ideal material for marine applications.

Fisheries Ropes and Fishing Nets : Used to manufacture deep-sea aquaculture cages, offshore fishing nets, high-strength cables, and more. Its lightweight and high-strength properties significantly reduce operational loads while enhancing durability.

Marine mooring ropes : Used as ship cables, tow ropes, sailing rigging, and more, it boasts significantly higher strength than steel cables—while weighing the same—and is also much easier to handle.

Marine Engineering : Used for mooring cables, underwater robot slings, and more.

3. Industry and Transportation Sector

It primarily leverages its high wear resistance, self-lubricating properties, and fatigue resistance to extend equipment lifespan and enhance efficiency.

High-performance conveyor belt : Designed for harsh environments such as mines and ports, it is lighter, more wear-resistant, and consumes less energy compared to traditional conveyor belts.

Lifting slings and ropes : Used for heavy equipment handling, aerospace vehicle lifting, rescue towing, and more—featuring a high safety factor and preventing damage to equipment surfaces, unlike steel cables.

Industrial Wear-Resistant Lining : Used as linings in silos, chutes, and bulk carriers to prevent material adhesion and abrasion.

4. Aerospace and Specialized Equipment

In fields with high demands for weight reduction and strength.

Parachute cord : High strength yet lightweight, with exceptional reliability.

Armored materials : Lightweight composite armor designed for helicopters, armored vehicles, and more, offering excellent protection performance.

Various types of specialized equipment cables : Used for various defense applications such as airdrops, towing, and supporting camouflage nets.

5. Sports and Outdoor Products Sector

Providing lightweight, high-strength, and impact-resistant solutions for high-end sports equipment.

High-performance ropes : Climbing ropes, paragliding lines, and more—these demand high strength-to-weight ratios and safety factors.

Enhanced Sports Equipment : Used as a reinforcing material for skis, bicycle rims (tire cords), windsurf boards, bowstrings, and more—greatly reducing weight while enhancing performance.

Protective equipment Such as horse-racing attire, fencing suits, and jet-ski protective gear, among others.
