English name of PPS: Phenylene sulfide Specific gravity: 1.36 g / cm3 Molding shrinkage: 0.7% Molding temperature: 300-330 ° C. It is a thermoplastic special engineering plastic with excellent comprehensive performance. Its outstanding features are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. Linear PPS is cross-linked at 350 ° C to form a thermosetting plastic. Branched structure PPS is a thermoplastic. PPS was first industrialized by Phillips in the United States in 1971. After the patent expired, Japanese companies began to develop and produce. Typical Japanese companies are Toray Corporation of Japan. At this stage, the output of Japan is already larger than that of the United States. Some other manufacturers are mainly concentrated in the United States and Japan. Western European countries do not currently produce PPS. China's Tianjin Synthetic Materials Research Institute, Guangzhou Chemical Reagent Factory, Sichuan Zigong Chemical Reagent Factory, Hebei Institute of Technology and Guangzhou Chemical Research Institute and other units had a small amount of production. At present, domestic PPS agents include Shanghai Lianmo Chemical, By 2000, the world's PPS output could reach 50,000 tons / year. The largest demand for PPS is Japan with 33%, North America with 32%, Western Europe with 19%, and Asia-Pacific with 16%.
