ERTACETAL C Natural (white)/ black POM C
These are ERTA’s virgin copolymer (POM C) and homopolymer (POM H) acetal grades. The acetal copolymer is more resistant against hydrolysis, strong alkalis and thermal-oxidative degradation than the acetal homopolymer.
The latter, however, has higher mechanical strength, stiffness, hardness and creep resistance as well as lower thermal expansion rate and very often it also presents a better wear resistance.
ERTACETAL is very well suited for machining on automatic lathes and is particularly recommended for mechanical precision parts.
Precision gears, bearings with close tolerances, electrical engineering insulators, snap fit assemblies, parts which operate in water between 60°C to 80°C.
