Polyoxymethylene (Polyacetal) Ertacetal C, Ertacetal H
Polyacetal C, Ertacetal C is an acetal copolymer. It is suitable for contact with food products, it is highly processed, good electrical insulating and dielectric properties, good flow resistance, high impact strength, even at low temperatures, excellent elasticity, more resistant to hydrolysis, strong alkalis and thermo-oxidative degradation than the acetal homopolymer.
Polyacetal H, Ertacetal H is an acetal homopolymer. It has higher mechanical strength, stiffness, hardness and creep resistance, as well as lower coefficient of thermal expansion and often higher wear resistance than acetal copolymer.
