Description
Polyoxymethylene (POM), also known as Delrin or Acetal, is a high-performance thermoplastic with excellent strength, stiffness, low friction, and wear resistance.
POM Homopolymer (Delrin-H): Higher mechanical strength and dimensional stability, continuous use up to 100–120°C.
POM Copolymer (Delrin-C): Better chemical resistance and impact performance at low temperatures, continuous use up to ~100°C.
POM is available in sheets, rods, and tubes, easy to machine and fabricate, and ideal for gears, bearings, sliding parts, and precision components across automotive, electrical, and industrial applications.
