POM: Polyoxymethylene is a linear polymer with no side chains, high density, and high crystallinity. According to the chemical structure in the molecular chain, it can be divided into two types: homopolyformaldehyde and acetal copolymer. The important difference between the two is that the homopolyformaldehyde has high density, crystallinity and melting point, but the thermal stability is poor, the processing temperature range is narrow (about 10 ° C), the acid-base stability is slightly lower, and the copolymerized formaldehyde density, crystallinity, 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 ° C), and the acid-base stability is good. It is an engineering plastic with excellent comprehensive performance. Has good physical, mechanical and chemical properties, especially with excellent friction resistance. Commonly known as Saigang or Steel, it is the third largest general plastic. Suitable for making wear-resistant parts, transmission parts, and parts such as chemicals and instruments.1. High mechanical strength and rigidity;2, the highest fatigue strength;3. Good environmental resistance and organic solvent resistance;4, strong resistance to repeated impact;5, a wide range of operating temperatures (-40 ° C ~ 120 ° C); 6, good electrical properties;7. Good recovery;8. It has good self-lubricating and wear resistance;9, excellent dimensional stability. ApplicationPOM can replace most non-ferrous metals, automobiles, machine tools, instrument parts, bearings, fasteners, gears, springs, pipes, conveyor belt accessories, electric water tanks, pump casings, drainers, faucets, etc. 1: Electronics: washing machine, juice machine parts, timer components2: Auto: handlebar parts, electric window parts3: Industrial parts: mechanical parts, gears, handles, toys, screws
