What is the difference between POM plastic and PE plastic.

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 its thermal stability is poor, the processing temperature range is narrow (about 10℃), and the stability to acid and alkali is slightly lower; while the 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.
PE (Polyethylene abbreviated as pe)

Polyethylene, Referred to as pe) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can withstand most acids and alkalis. It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation. The mechanical properties of polyethylene are general, the tensile strength is low, the creep resistance is not good, and the impact resistance is good. Polyethylene can be processed by blow molding, extrusion, injection molding and other methods, and is widely used in the manufacture of films, hollow products, fibers, and daily sundries.
