Viva Nylons Limited POM-C (Acetal)
Viva Nylons Limited POM-C (Acetal) otherwise known as Acetal Copolymer features highly crystalline resins, making this material strong and rigid, with a low coefficient of friction in comparison to metals and other plastics. POM-C is also creep resistant and is recommended for applications where dimensional stability is important. 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.
