UHMWPE= Ultra-high molecular weight polyethylene whose molecular weight is more than 2.5 million 

UHMWPE is a thermoplastic engineering plastic with a viscosity-average molecular weigh greater than 1.5×106, and is made by polymerization of ethylene under the action of a catalyst. Its molecular weight has reached over 5 million, its five properties of abrasion, impact and corrosion resistance, self-lubrication, and absorption of impact energy are the best among the available plastics.

Characteristics:

1. Outstanding impact strength even at very low temperature. 2. Excellent sliding abrasion resistance, wear strength several times as large as steel. 3. Very low coefficient of friction. 4. Nonstick, self-lubrication properties. 5. Good chemical resistance. 6. Excellent anti-aging. 7. Hygienic and nontoxic 8. Lightweight. 9. Hydrophobic, energy absorption and sound-dampening properties. 10. Excellent dielectric and insulating properties.
