POM ABS PP Turning Milling Black High Precision Parts

Definition of POM (polyoxymethylene resin): Polyoxymethylene 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.
