Polyoxymethylene (POM) Resin CAS 9002-81-7

Polyoxymethylene (POM), also known as polyacetal, acetal resin or polyformaldehyde, is a high-performance engineering thermoplastic with excellent mechanical strength, dimensional stability, low friction and good wear resistance. It is commonly supplied as plastic resin granules for injection molding and extrusion applications. POM is widely used in precision mechanical parts, gears, bearings, automotive components, electrical parts, industrial mechanisms and consumer product components.
