What is the shrinkage rate of plastic POM+30GF?

POM (polyoxymethylene resin) definition: POM is a linear polymer with no side chains, high density and high crystallinity. According to the different chemical structure in its molecular chain, it can be divided into two types: homopolyoxymethylene and copolyoxymethylene. The important difference between the two is: homopolyoxymethylene has high density, crystallinity, and melting point, but poor thermal stability, narrow processing temperature range (about 10℃), and slightly lower stability to acid and alkali; while copolyoxymethylene has high density, crystallinity, and The melting point and strength are low, but the thermal stability is good, it is not easy to decompose, the processing temperature range is wide (about 50 ℃), and the stability to acid and alkali is good. It is an engineering plastic with excellent comprehensive properties. It has good physical, mechanical and chemical properties, especially excellent friction resistance. Commonly known as Saigang or Duogang, it is the third largest general-purpose plastic. It is suitable for making wear-reducing and wear-resistant parts, transmission parts, and chemical, instrument and other parts.
