UHMW-PE grades offered by Mitsui meet diverse industry needs due to the material's excellent chemical resistance, abrasion resistance, impact resistance and self-lubrication properties.

Physical Properties of LUBMER™

LUBMER™ is a strong material with good impact and mechanical strength. It is light weight with good chemical heat and water resistance. Due to LUBMER™'s extremely low friction properties, LUBMER™ is a good alternative to fluoropolymers, where the improvement of wear resistance and reduced cost is required. Table 3 summarizes the key physical properties of some LUBMER™ grades.
