Delrin Plastic Resin Balls
Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability. As many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and is therefore sold under many commercial names like Delrin, Celcon, Hostaform, etc.
POM is characterized by its high strength, hardness and stiffness to ~40ºC. POM 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 semi-crystalline polymer (75-85% crystalline) with a melting point of 175ºCelsius. The POM copolymer has a slightly lower melting point of 162-173ºCelsius.
POM is a tough material with a very low coefficient of friction. Our inventory of Delrin bearing balls ranges from 9/32 in. to 1 1/2 inches and available in a variety of colors inclyding white, black, yellow, and red.
