Product Description
PPS plastic raw material English name: Phenylenesulfide specific gravity: 1.36g/cc Shape shrinkage: 0.7%
Molding temperature: 300-330oC. It is a thermoplastic special engineering plastic with excellent comprehensive performance. Its outstanding characteristics are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. The linear PPS becomes thermosetting plastic after crosslinking above 350oC, and the branched structure PPS is thermoplastic. PPS was first manufactured by Philip Company in 1971. After the patent expired, Japanese companies began to develop and produce PPS. A typical Japanese enterprise is Toray Company of Japan. At present, the output of Japan is larger than that of the United States. Other manufacturers are mainly concentrated in the United States and Japan, western European countries do not produce PPS now.
PPS is called polyphenylene sulfide in Chinese. It has the advantages of hard and brittle, high crystallinity, non-combustible, good thermal stability, high mechanical strength, excellent electrical properties, strong chemical corrosion resistance and so on. PPS is one of the best varieties of heat resistance in engineering plastics, the thermal deformation temperature of the material modified by glass fiber is generally greater than 260 degrees, and the chemical resistance is second only to ptfe. In addition, it also has a small molding shrinkage, low water absorption, good fire resistance. Good vibration resistance fatigue, arc resistance and other advantages, especially at high temperature. Excellent electrical insulation in high humidity. But its disadvantages are brittleness, poor toughness, low impact strength, after modification, can overcome the above shortcomings, obtain very excellent comprehensive performance

ApplicationPPS, also known as polyphenylene sulfide, is a crystalline type (55%-65% crystallinity) of high rigid white powder polymer, high heat resistance (continuous use temperature up to 240), mechanical strength, rigidity, non-flammability, electrical characteristics, dimensional stability are excellent resin, wear resistance, creep resistance, flame retardant. Self-extinguishing, up to UL94V-0 grade. Good electrical performance under high temperature and high humidity. Good fluidity, easy to shape, forming almost no shrinkage concave spot. It has good affinity with various inorganic fillers. Its development shortens the difference between standard thermoplastic materials (e.g., PA, POM, PET) and advanced engineering plastics.Features: Maximum allowable working temperature is very high in the air, can continue to work in 240, short time of up to 260), the environment of high temperature to keep high mechanical strength, stiffness and hardness, excellent corrosion resistance and resistance to hydrolysis performance (can be found under 200 polyphenylene sulfide (PPS) solvent, dissolving the strong inorganic acid, alkali and salt resistance), excellent wear resistance and frictional, Very good dimensional stability, excellent resistance to high energy radiation, good uv resistance, its own flame retardant, excellent electrical insulation.
Application: electronic, electrical: micro electronic components package, coil frame, motor shell, relay, trimmer capacitor and other parts. Precision instruments: computer, timer, photocopier, temperature sensor and the housing and parts of various measuring instruments. Machinery: pump shell, pump wheel, valve, fan, flow meter parts, flange, universal head. Automobile:, clutch, transmission, gearbox, bearing support, exhaust system parts.Product Parameters
