Engineering Plastic
UHMWPE SHEET & ROD
1. UHMW-PE is a thermoplastic engineering plastic which is polymerized by ethylene and butadiene monomer under the action of catalyst. The average molecular weight is more than 3.5million-7.0million.
2. The product combines the superior performance of many plastics, have excellent wear resistance, impact resistance, chemical corrosion resistance, low temperature resistance, self-lubricity and other characteristics.
3. Low friction coefficient, high wear resistance, high impact resistant.
4. Excellent chemical stability. It can improve the corrosion resistance and anti-static performance by adjusting the formula.
5. The temperature range:-150ºC to +80ºC
6. Low water absorption.
