Raw materials and products of PPS plastics

2017-11-29

English name of pps plastic raw material: Phenolenesulfide Specific gravity: 1.36g/cm3 Molding shrinkage: 0.7% Molding temperature: 300-330 ℃. It is a kind of thermoplastic special engineering plastic with excellent comprehensive properties, and its outstanding characteristics are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. Linear PPS becomes thermosetting plastic after cross-linking at above 350 ℃, and branched chain PPS is thermoplastic plastic. PPS was first industrialized by Philips in 1971. After the technology expired, Japanese enterprises began to research, develop and produce PPS. The typical Japanese enterprise is Toray Company of Japan. At this stage, the output of Japan is larger than that of the United States. Other manufacturers are also mainly concentrated in the United States and Japan, and western European countries do not produce PPS now. PPS plastic

The Chinese name of PPS is polyphenylene sulfide. It has the advantages of hard and brittle, high crystallinity, flame retardant, good thermal stability, high mechanical strength, excellent electrical performance, strong chemical corrosion resistance, etc. PPS is one of the varieties with good heat resistance in engineering plastics. The thermal deformation temperature of glass fiber modified materials is generally higher than 260 ℃, and the chemical resistance is only inferior to that of polytetrafluoroethylene. In addition, it also has the advantages of small molding shrinkage, low water absorption, good fire resistance, good vibration fatigue resistance, strong arc resistance, etc., especially in the high temperature and high humidity environment, it still has good electrical insulation. However, its disadvantages are high brittleness, poor toughness and low impact strength. After modification, it can overcome the above shortcomings and obtain excellent comprehensive properties.
