Phenylenesulfide specific gravity: 1.36 g/cm3 shrinkage rate:0.7%Molding temperature: 300-330℃. It is a kind of thermoplasticspecial engineering plastic with excellent comprehensiveperformance. Its outstanding characteristics are high temperatureresistance, corrosion resistance and superior mechanicalproperties. PPS is sulfur-containing aromatic polymer, linear PPScrosslinked at 350℃ or more into thermosetting plastic, branchedchain structure PPS for thermoplastic.PPS is called polyphenylenesulfide in Chinese. It is hard and brittle, high crystallinity,difficult to burn, good thermal stability, high mechanicalstrength, excellent electrical performance, chemical corrosionresistance and other characteristics. PPS is one of the varietieswith the best heat resistance in engineering plastics. The thermaldeformation temperature of materials modified by glass fiber isgenerally greater than 260 degrees, and its chemical resistance issecond only to polytetrafluoroethylene. In addition, it also has asmall shrinkage molding, low water absorption, good fireresistance. Good shock fatigue resistance, strong resistance toelectric arc, especially at high temperature. Excellent electricalinsulation in high humidity. However, its disadvantages are largebrittleness, poor toughness and low impact strength. Aftermodification, the above disadvantages can be overcome and excellentcomprehensive performance can be obtained
