Polyoxymethylene (POM) is mainly concentrated in the low-end field. Domestic high-end products still rely on imports.

Polyoxymethylene (POM), also known as acetal resin and polyoxymethylene, is a linear polymer with high density, high thermoplasticity and high crystallinity. According to different properties, polyoxymethylene can be divided into two categories: homopolymer and copolymer. Polyformaldehyde has the characteristics of high crystallinity, high melting point, good thermal stability, strong bending resistance, and good fatigue resistance.…
