Ertacetal H (POM-H) is Mitsubishi Chemical Group homopolymer acetal grade. It offers a higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate and often also a better wear resistance than the acetal copolymer.
Ertacetal provides high mechanical strength and stiffness coupled with enhanced dimensional stability. As a semi-crystalline material, Ertacetal is characterized by a low coefficient of friction and good wear properties.
