Polyurethane mechanical parts are mechanical parts made of polyurethane material. Polyurethane mechanical parts have excellent wear resistance and durability. Able to maintain stable performance for a long time in harsh working environments. In addition, polyurethane also has good corrosion resistance and oil resistance, can resist the erosion of chemicals and grease, and prolongs the service life of mechanical parts. Polyurethane mechanical parts are widely used in machinery manufacturing, automobile manufacturing, petrochemical industry and other fields. For example, in automobile manufacturing, polyurethane can be used to make seals, shock absorbers, brake pads and other components: In machinery manufacturing, polyurethane can be used to manufacture bearings, gears, chains and other components.
