Chain guide
The chain guide rail is a polyethylene variety with ultra-high molecular weight (usually over 1.5 million). It has excellent impact resistance and self-lubrication. The extremely high molecular weight of UHMWPE endows it with excellent performance, and it is a thermoplastic engineering plastic with moderate price and excellent performance. It almost combines the advantages of various plastics and has comprehensive properties such as wear resistance, impact resistance, self-lubrication, corrosion resistance, impact energy absorption, low temperature resistance, less adhesion, less water absorption, and low density that ordinary polyethylene and other engineering plastics cannot compare. In fact, there is no single polymer material that possesses so many excellent properties.
