Product Description
Polyoxymethylene, commonly known as POM, it is a thermoplastic engineering plastics with high melting point and high crystallinity, a yellowish or white crystalline polymer with smooth and dense surface. According to the chemical structure of molecular chain, it can be divided into polyformaldehyde copolymer and polyformaldehyde homopolymer.
Comparing the properties of polyformaldehyde copolymer with polyformaldehyde homopolymer, some properties of copolymer are superior to homopolymer such as low melting point, thermal stability, chemical resistance, liquidity, hydrolysis resistance, acid and alkali resistance, superior process ability. However, some properties of homopolymer are also better than copolymer including high crystallinity, creep resistance, lower thermal expansion, abrasion resistance, good mechanical strength, high rigidity and so on.
