POM C

Acetal Copolymer

Polyethylene

The Copolymer grade is the ideal combination of strength, stiffness and wears resistance. It absorbs very little moisture, is easily
machinable and is genuinely porosity-free making it the preferred grade for food contact and medical applications. The product exhibits an
elevated resistance to hydrolysis, strong alkalis and thermal-oxidative degradation when compared to acetal homopolymer.
