Ultra High Molecular Weight Polyethylene（UHMEPE）

Ultra-high molecular weight polyethylene fiber (UHMWPEF), also known as high-strength, high-modulus polyethylene fiber, boasts the highest specific strength and modulus in the world. It is spun from polyethylene with a molecular weight of 1 million to 5 million.

Physical Propertie：

Density: 0.97-0.98 g/cm³.

Tensile Strength:3Gpa

Modulus:100Gpa.

Elongation: 3.5%-3.7%.

Melting Point: 145-160°C.

Special Properties：

1. High specific strength and modulus. Its specific strength is over ten times that of steel wire of the same cross-section, and its specific modulus is second only to premium carbon fiber.

2. Low fiber density, 0.97-0.98 g/cm³, allows it to float on water.

3. Low elongation at break and high work of fracture, resulting in strong energy absorption and outstanding impact and cut resistance.

4. Resistant to UV radiation, neutrons, and gamma rays, it offers high specific energy absorption, a low dielectric constant, and high electromagnetic wave transmittance.

5. Chemical and abrasion resistance, with a long flex life.

Application Prospects：

Due to its numerous excellent properties, ultra-high molecular weight polyethylene (UHMWPE) fiber demonstrates significant advantages in the high-performance fiber market, ranging from offshore oilfield mooring ropes to high-performance lightweight composite materials. It plays a crucial role in modern warfare, aviation, aerospace, and maritime defense equipment.
