Acetal Copolymer 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.
