Product Name: polyphenylene sulfide, polyphenylene sulfide of a new type of high performance thermoplastic resin is a crystalline polymer. The unstretched fibers having a larger amorphous region (degree of crystallinity of approximately 5%), at **5 ℃ crystallization exotherm occurs, the glass transition temperature of *3 ° C; m.p. **1 ° C. Stretched fibers in the stretching process to produce a partially crystalline, (increased to *0%), such as the stretched fiber at a temperature of ******0 ℃ heat treatment, to enable the degree of crystallization, increased by ****0%. Therefore, of the fiber after stretching is no apparent glass transition or crystallization exotherm, a melting point of **4 ° C. With the improvement of the degree of crystallinity after tensile heatsetting, the density of the fibers also increases accordingly, before stretching 1.*3g/cm3 after stretching 1.*4g/cm3, after heat treatment is up to 1.*8g/cm3. PPS is a comprehensive performance of special engineering plastics. PPS has excellent high temperature resistance, corrosion resistance, radiation resistance, retardant balanced physical and mechanical properties and excellent dimensional stability and excellent electrical performance characteristics, is widely used as a structural polymer material through the fill, change special engineering plastics are widely used as sex. At the same time, can also be made ​​of the various functional films, coatings and composites, to be successful in the field of electronic appliances, aerospace, automotive and transportation applications. In recent years, the domestic enterprises to actively research and development, and the initial formation of a certain production capacity, situation changed completely dependent on imports. However, PPS technology there is less product variety, high-function products less urgent capacity enlargement, these PPS next step in the development of the focus.
