UHMW-PE (Ultra High Molecular Weight Polyethylene) is thermoplastic engineering plastics, which is normally used in the area of marine, transport, coal-mining, machinery, paper-making, textile industry, etc.
Features of UHMWPE Sheets and Components:
· Very low friction coefficient
· High impact strength without breaking or shattering
· High abrasion resistance
· Chemically inert, suitable for nearly all chemicals, including HCL
· Survive in Freezing Conditions from ( -200 Degree C to 80 Degree C )
· Anti-stick properties and self-lubricating materials

As a new type of engineering plastic, UHMWPE sheet possesses multiple performance advantages:
Extraordinary wear-resistant,4~6 times higher than other plastic,6~9 times higher than steel, and 26 times higher than copper.
Highly impact strength, 10 times higher than PA6 and PP
Low friction coefficient (0.05~0.11), and capable of self lubrication
Unattractive to foreign material, and anti-sticking while sliding
Resistant to chemical corrosion
