POM聚甲醛(杜邦100P)
聚甲醛(POM)
聚甲醛学名聚氧化聚甲醛(简称POM)又称赛钢、特钢。它是以甲醛等为原料聚合所得。POM-H(聚甲醛均聚物),
POM-K(聚甲醛共聚物)是高密度、高结晶度的热塑性工程塑料。具有良好的物理、机械和化学性能,尤其是有优异的耐摩擦性能。
聚甲醛是一种无侧链高密度结晶性聚合物,具有优异的综合性能。
聚甲醛是一种表面光滑,有光泽的硬而致密的材料,淡黄或白色,可在-40- 100°C温度范围内长期使用。
它的耐磨性和自润滑性也比绝大多数工程塑料优越,又有良好的耐油,耐过氧化物性能。很不耐酸,不耐强碱和不耐紫外线的辐射。(加入UV剂,能大大提高其耐紫外线等级)

Physical properties, pom tensile strength of 70 MPA, waterabsorption, size stability, luster, these properties are betterthan nylon, pom is a highly crystalline resin, in thermoplasticresin is tough. With heat resistance, bending strength, fatiguestrength are high, wear resistance and excellent electricalproperties. Pom Products, process conditions, drying: if thematerial is stored in a dry environment, it usually does notrequire drying. Melting temperature: HOMOPOLYMER MATERIAL IS 190 ~230 °C, copolymer material is 190 ~ 210 °C. MOULD TEMPERATURE: 80 ~105 °C. In order to reduce the shrinkage after forming can choose ahigher mold temperature. PRESSURE: 700 ~ 1200 BAR, speed: medium orhigh, speed. Runner and gate: Any type of gate may be used. If atunnel gate is used, a shorter type is used. For homopolymermaterials, hot nozzle runner is recommended. For the COPOLYMERmaterial, either internal hot runner or external hot runner can beused.
