Polyformaldehyde (English: polyformaldehyde) thermoplastic crystalline polymer. Known as "super steel" or "sai steel", also known as polyoxymethylene. The English abbreviation is POM. Generally, the polymer obtained by the polymerization of formaldehyde has a low degree of polymerization and is easily depolymerized by heat. It can be used as a raw material for organic chemicals and synthetic resins, as well as a fumigant for medicines.
Polyoxymethylene is a hard and dense material with a smooth, shiny surface, light yellow or white, and the thin wall part is translucent. The burning characteristic is easy to burn. It will continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. Melting and dripping occur. There is a strong pungent formaldehyde smell and fishy smell.
POM has high strength and rigidity, good elasticity, and good wear resistance. Its mechanical properties are excellent, the specific strength can reach 50.5MPa, the specific stiffness can reach, and it is very close to metal. The mechanical properties of POM change little with temperature, and the change of copolymerized POM is slightly larger than that of homopolymerized POM. The impact strength of POM is higher, but the conventional impact is not as good as ABS and PC; POM is sensitive to notches, which can reduce the impact strength by as much as 90%.
