Polyoxymethylene is a technical name for polyoxymethylene (POM), also known as steel, special steel. It is obtained by polymerization such as formaldehyde as raw materials. POM-H (polyoxymethylene homopolymer), POM-C is a high density, high crystallinity thermoplastic engineering plastics. Good physical, mechanical and chemical properties, especially excellent friction resistance.

POM is a kind of side chain high density crystalline polymer, with excellent comprehensive performance.

POM is a kind of smooth surface, shiny hard and dense materials, yellowish or white or black, can be in - 40-100 ° C temperature range for long-term use. Its abrasion resistance and self - lubricity are also better than most engineering plastics, and has good oil and peroxide resistance. Very resistant to acid, strong alkali and uv radiation, mainly used in high-pressure conditions.
