Ultrahigh molecular weight polyethylene is a thermoplastic engineering plastic, which integrates the superior properties of all plastics, and the five characteristics of impact resistance, wear resistance, chemical corrosion resistance, self-lubrication, impact absorption performance and is the highest value of all existing plastics. Ultrahigh molecular weight polyethylene can even be used in liquid nitrogen or liquid helium, its use temperature can reach below -269 ℃, still has a certain mechanical strength.
Ultrahigh molecular weight polyethylene has excellent wear resistance, the higher the molecular weight, the better the wear resistance of the material. Ultrahigh molecular weight polyethylene has very low water absorption. Ultrahigh molecular weight polyethylene chemical stability is very high, in a certain temperature, concentration range can resist acid, alkali, salt and other corrosive media. Ultrahigh molecular weight polyethylene is tasteless, non-toxic, odorless and itself non-corrosive. The US Food and Drug Administration and the US Department of Agriculture allow it to be used in contact with food and drugs. Therefore, it is used in food, medicine and other industries that require higher health conditions.
Ultra high molecular weight polyethylene slide plate is a new polymer wear-resistant material specially developed by our company for bridge bearings. Mainly used in railway, highway bridge support, light rail, building seismic sliding block, etc. The UHMWPE product has the characteristics of high compressive strength, low friction coefficient, strong wear resistance, aging resistance and low temperature impact resistance. The product has passed the initial static friction coefficient and line wear rate (50km) test of National Railway Product Quality Supervision and Inspection Center and has been applied to high-speed rail, subway and other emerging fields.
