Delrin (Acetal Homopolymer) Balls Supplier
Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts where high stiffness, low friction, and excellent dimensional stability are required. As many other synthetic polymers, Acetal Homopolymer is produced by various chemical firms with varying formulas and under many commercial names, such as Delrin, Celcon, Hostaform, etc.
POM, characterized by its high strength, hardness, and stiffness to ~40ºC., is intrinsically opaque white, but it is available in all colors. POM has a density of 1.410-1.420 g/cm³.
POM homopolymer is a semicrystalline polymer (75-85% crystalline) with a melting point of 175ºCelsius. The POM copolymer has a slightly lower melting point of 162-173ºCelsius.
