UHMWPE Yarn

-- Steady & Reliable Manufacturer --

Introduction

UHMWPE (Ultra-High Molecular Weight Polyethylene) Yarn is the "miracle fiber" of the modern era. Often referred to as the world's strongest fiber, it is 15 times stronger than steel by weight and even stronger than Aramid. GC FIBER’s UHMWPE is produced via a gel-spinning process that creates extremely long, aligned polymer chains. This results in a yarn with a density lower than water (0.97 g/cm3), meaning it floats, yet it possesses incredible resistance to abrasion, moisture, and UV radiation.

Unlike Aramid, UHMWPE is highly resistant to chemicals and sunlight, making it the preferred choice for marine environments. Its low coefficient of friction makes it "colder" to the touch and extremely "slippery," which is why it is often used in premium cooling fabrics and high-performance fishing lines.

Fishing Gear: Deep-sea aquaculture cages, high-strength deep-sea fishing nets.

3. Sports and Outdoors

Competitive Equipment: High-performance fishing lines (Dyneema lines), bowstrings, parachute lines.

Sports Equipment: Rowing cables, professional climbing ropes.

4. Industrial and Civilian Use

Special Lifting Equipment: Industrial lifting slings (high load-bearing capacity without damaging surfaces).

Home Textiles: Cooling mats, cooling blankets (utilizing their high thermal conductivity).

5. Medical Field
Human Repair: Medical sutures, artificial ligaments, artificial joint reinforcement.

Advantage

Ultra-high strength: With the same mass, its tensile strength is approximately 15 times that of high-quality steel, making it one of the strongest fibers in the world.

Extremely lightweight: Lighter than water, it floats on water, making it extremely easy to handle and transport.

Excellent abrasion resistance: It has an extremely low coefficient of friction and extremely strong abrasion resistance, far exceeding that of traditional fibers such as nylon and polyester.

Chemically inert: Resistant to acids, alkalis, salts, and various organic solvents; its physical properties are extremely stable even in harsh environments.

UV resistance: It has natural resistance to ultraviolet radiation; its strength decreases very little after long-term exposure to strong light, resulting in a long service life.

High thermal conductivity: It dissipates heat quickly, giving fabrics a natural "cooling" feel, making them cool and comfortable to the touch.

Impact resistance: It can absorb extremely high amounts of energy, performing exceptionally well in bulletproof, stab-proof, and industrial impact protection applications.

Payment and Shipping

Standard shipping in export-grade cartons. Lead times: 20−30 days. T/T payments preferred.

Common Questions

  • Q: Does it melt?
  • A: Yes, it has a lower melting point (150∘C) compared to PET, so it is not for high-heat environments.
  • Q: Is this yarn difficult to dye?
  • A: It's very difficult. UHMWPE is chemically inert, and common chemical dyes cannot adhere to it.
  • Q: Is it abrasion-resistant? Can it be used for cut protection?
  • A: It is one of the most abrasion-resistant thermoplastic materials available (15 times more abrasion-resistant than carbon steel). In the glove industry, it is widely used to manufacture level 3-5 protection cut-resistant gloves, providing excellent protection when handling glass or sharp metals.
  • Q: How long is its lifespan? Will it be damaged by sunlight?
  • A: Much longer than ordinary plastics. It has excellent UV resistance, and its strength decays very slowly with prolonged exposure to sunlight. Under normal marine or outdoor conditions, its lifespan is typically 2-3 times that of steel cables or nylon ropes.
