POM plastic materials properties: 
 POM (English: polyformaldehyde) a thermoplastic crystalline polymer. Known as the "super steel" or "match steel, also known as polyethylene oxide, methylene. The abbreviation for the POM. Usually formaldehyde polymerization from the polymer, the degree of polymerization is not high, and susceptible to thermal depolymerization. 
 POM is a surface smooth, shiny, hard and dense material, yellow or white, can be long-term use in the -40-100 ° C temperature range. Its wear resistance and lubricity superior than most other engineering plastics, there are good oil, peroxide-resistant performance. Very acid, of intolerance alkali and intolerance sunlight UV radiation. 
 POM of the tensile strength up to 70MPa, water absorption, dimensional stability, glossy, these performance than nylon, POM is a highly crystalline resin in the thermoplastic resin is the toughest. With the thermal strength, flexural strength, fatigue resistance are high strength, abrasion resistance and excellent electrical properties 
 POM plastic materials processing conditions 
 POM has a low coefficient of friction and the geometric stability, particularly suitable for the production of gears and bearings. It also has a high temperature characteristics, it is also used for pipe device (pipe valve, pump housing), lawn equipment, etc.. Injection Molding Processing Conditions: Dry processing: If the material is stored in a dry environment, usually does not require drying. The melting temperature: homopolymer materials for 190 ~ 230 ℃; copolymers for 190 ~ 210 ℃. Mold temperature: 80 ~ 105 ℃. In order to reduce the molding shrinkage can choose a higher mold temperature. Injection pressure: 700 ~ 1200bar. Injection speed: moderate or high injection speed.
