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.

Comapring 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 resisitance, alkali resistrance, 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 resisitance, good mechanical strength, high rigidity and distortion temperature.

Our company can pruduce high quality POM-C rods and POM-H rods.

Our POM rods and sheets have Good roundness and straightness are very suitable for automatic lathe processing, and have good dimensional stability.
