Polyoxymethylene Poly(oxymethylene), Copolymer (POM-C)
Poly(oxymethylene) is an acetal plastic based on polymers in which oxymethylene is essentially the sole repeating structural unit in the chains. A copolymer is a long-chain molecule formed by the reaction of two or more dissimilar monomers (Glossary of Terms). POM-C has improved mechanical properties versus the homopolymer. It is used for fabrication of molded device components (e.g., heart valve occluders), and bearing surfaces. Its resistance to degradation depends on hydrolytic stability of the chain extender (Gibbons 2008).
