UHMWP
- Ultra-high molecular weight polyethylene is a linear thermoplastic engineering plastic. Its core characteristic is extremely high molecular weight, typically above 1.5 million. This ultra-long molecular chain structure endows it with a series of exceptionally superior properties, making it an ideal alternative to metals, other plastics, and even ceramics in many harsh operating conditions.
