Brief Introduction of POM Balls
POM ball is Polyacetal ball. The polyoxymethylene is obtained from the polymerization of formaldehyde, and it is thermoplastic engineering plastic with high density and high crystallinity. It also has good physical, mechanical and chemical properties, especially excellent abrasion resistance. Its advantages are high strength and rigidity, good wear resistance, small water absorption and good dimensional stability. However, the thermal stability is poor and it’s easy to burn. POM balls are suitable for the production of wear-resistant parts, transmission parts, as well as instrumentation and other parts.
