As UHMW-PE has an extremely low friction coefficient (0.1-0.22), its self lubrication is excellent. Dynamic friction factor is 1/2 of PA66 and POM under water lubrication conditions. When UHMW-PE and steel, copper pairing are used, it is difficult to produce adhesive wear, and wear on mating parts is small. Therefore, UHMW-PE is known as the friction material with extremely ideal cost performance in the field of friction.
