Shanghai Daoqin Plastics Co., Ltd.

　 USA DuPont pom就 is polyoxymethylene (POM) resin, it 定义: polyoxymethylene (POM) is types has 侧链, high density, high crystallization property type polymer. its separation in chemical structure different, can separation is POM copolymer and POM homopolymer types, although comparison versus 似, is has difference, below/following is difference.

　　 USA DuPont pom500P production manufacturer tells you POM copolymer and POM homopolymer important difference is: POM copolymer density, crystallization degree, melting point, strong/high degree relatively low, heat stabilized property good, easy separation understanding, processing temperature degree scope/range wide (约50℃), for acid alkali stability property relatively good. is tool has excellent comprehensive property can engineering plastics. has good material 理, machine and chemical property can, especially is has excellent resistant scratch property can. 俗称赛钢 or 夺钢, is large general purpose plastics. made as decrease abrasion wear resistant parts, parts, and chemical industry, table/sheet and other parts.

　　 POM homopolymer density, crystallization degree, melting point high, heat stabilized property 差, processing temperature degree scope/range narrow (约10℃), for acid alkali stability property low.

　　 USA DuPont pom500P is DuPont production excellent USA DuPont pom plastics, 由东莞市振邦 plastics raw materials has company is a large amount of supply. to large introduction USA DuPont pom500P plastics raw materials has which advantages and

　　 USA DuPont pom500P advantages has below/following 几点

　　一, tool has high temperature resistance features, therefore also used for pipeline device parts (pipeline 阀门, housing/shell 体), equipment and other.

　　二, crystallization property plastics, melting point obvious, 一旦达 to melting point, melt viscosity speed decline.

　　三, USA DuPont pom500P is types tough has elastic property material, make in low temperature lower still has very good resistant creep features, stability property and impact resistant features.

　　四, high crystallization degree it has versus high shrinkage rate, can high to 2%~3.5%. for/regarding various different reinforcement type material has different shrinkage rate.

　　五, tool has very low friction coefficient and very good stability property, especially combined made as gears and bearings.
