POM Supplier Engineering Polymer Polyoxymethylene Granules Recycled Virgin Plastic Pom for Molding High Grade

POM (Polyoxymethylene, abbreviated as POM) is a linear polymer with no side chains, high density, and high crystallinity. It is divided into two types: homopolymer formaldehyde and copolymer formaldehyde. Homoformaldehyde has high density, high crystallinity, and high melting point, but its thermal stability is poor; And co formaldehyde has good thermal stability and a wide processing temperature range. POM is a hard and dense material with a smooth and glossy surface, light yellow or white, and can be used for a long time in the temperature range of -40-100 ° C. It has good wear resistance, self-lubricating properties, and oil resistance, but is not resistant to acid, strong alkali, or ultraviolet radiation
