Physical Property
Rated Value
Polyphenylene sulfide is a thermoplastic resin with phenylsulfide group in the main chain. Polyphenylene sulfide is a crystalline polymer. The unstressed fiber has a large amorphous region (crystallinity is about 5%), crystallization exothermic occurs at 125 ℃, the glass transition temperature is 150 ℃, and the melting point is 281 ℃. During the drawing process, the tensile fiber produces partial crystallization (up to 30%). If the tensile fiber is heat treated at 130-230 ℃, the crystallinity can be increased to 60-80%.
Therefore, there is no obvious glass transition or crystallization exothermic phenomenon after drawing, and its melting point is 284 ℃. With the increase of crystallinity after drawing heat setting, the density of the fiber increases accordingly, from 1.33g/cm3 before drawing to 1.34g/cm3 after drawing, and it can reach 1.38g/cm3 after heat treatment. Molding shrinkage: 0.7%, molding temperature: 300-330 ℃.
