Acetal
AE stocks Ertacetal® C in colours natural and black.
The acetal copolymer (POM-C) is more resistant against hydrolysis, strong alkalis and thermal-oxidative degradation than the Acetal homopolymer (POM-H). The latter however has a higher mechanical strength, stiffness, hardness and resistance to creep, as well as a lower thermal expansion rate and often presents better wear resistance. Ertacetal® is very well suited for machining on automatic lathes and is recommended for mechanical precision parts.
Acetal is available in rod, tube and sheet, cut to size or machined to customer specification.
