Are there migratable organotin compounds in POM plastics?
POM (polyoxymethylene resin) definition: Polyoxymethylene is a linear polymer with no side chain, high density and high crystallinity. According to the difference of chemical structure in its molecular chain, it can be divided into two kinds of homopolymeric formaldehyde and copolymeric formaldehyde. The important difference between the two is that: homopolymer formaldehyde has high density, crystallinity and melting point, but poor thermal stability, narrow processing temperature range (about 10℃) and slightly lower stability to acids and bases; while copolymer formaldehyde has lower density, crystallinity, melting point and strength, but good thermal stability, not easy to decompose, wide processing temperature range (about 50℃) and better stability to acids and bases. It is an engineering plastic with excellent overall performance. It has good physical, mechanical and chemical properties, especially excellent friction resistance. It is commonly known as race steel or steel, and is the third most common engineering plastic. Suitable for the production of wear-resistant parts, transmission parts, and chemical, instrumentation and other parts.
It is a kind of synthetic resin, also known as polyformaldehyde resin, POM plastic, race steel material, etc.; it is a white or black plastic granule with high hardness, high steel and high wear resistance. It is mainly used for gears, bearings, automotive parts, machine tools, instrumentation and other products that play a skeleton role.
POM what type of material ah. It can replace most non-ferrous metals, automobiles, machine tools, instrument internals, bearings, fasteners, gears, spring plates, pipes, transportation belt fittings, electric boilers, pump housings, leachers, faucets, etc..
