White Black Color Pom Rod Length 1M ~ 2M Diameter 6mm ~ 120mm With Low Price
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 copolymer and homopolymer, some properties of copolymer are superior to homopolymer such as low melting point, thermal stability, chemical resistance, liquidity, hydrolysis resistance, alkalli resistance, thermal oxidization demotion and superior process ability. However, some properties of homopolymer are better than copolymer including high crystallinity, high creep, lower thermal expansion, abrasion resistance, good mechanical strength, high rigidity and distortion temperature.
