POM plastic material is a linear macromolecule compoundcontaining - CH2 - O - chain in the main chain of molecule. It isopaque crystalline linear thermoplastic resin. POM is a linearpolymer with no side group, high density and high crystallinity,and has excellent comprehensive properties. It is a kind ofexcellent resin developed after nylon. Its regular molecularstructure and crystallinity make its physical and mechanicalproperties very excellent. It is known as "metal plastics". POM canbe divided into homopolymer formaldehyde and copolymer formaldehydeaccording to the chemical structure of the molecular chain.Homopolymer formaldehyde is usually obtained by the polymerizationof anhydrous polyformaldehyde. Copolymer formaldehyde is theproduct of the copolymerization of trimethylformaldehyde and asmall amount of dioxane. It is precisely because of the differentstructure that the homopolymer and copolymer formaldehyde havedifferent properties. The main differences between them are: thedensity and crystallinity of homopolymer formaldehyde are higher,the melting point and HDT are 10 degrees higher than that ofcopolymer formaldehyde, the strength, creep resistance and frictionresistance are better, but the thermal stability is poor, theprocessing temperature range is narrow about 10 degrees, and thestability of acid and alkali is lower. The density, crystallinity,melting point and strength of copolymerized formaldehyde are low,but its thermal stability is relatively good, and it is not easy todecompose. The processing temperature range is 30-50 C, which hasgood acid-base stability.
