Engineering Plastic: UHMWPE SHEET & ROD
1. UHMW-PE is a thermoplastic engineering plastic polymerized by ethylene and butadiene monomer. Average molecular weight exceeds 3.5 million to 7.0 million.
2. Combines superior performance: excellent wear resistance, impact resistance, chemical corrosion resistance, and low temperature performance.
3. High self-lubricity with a low friction coefficient.
4. Working temperature range: -150ºC to +80ºC.
