Detailed Product Description: | Polyphenylene sulfide all known poly (phenylene sulfide) is a thermoplastic resin of the molecular main chain with a phenylthio, English name of polyphenylenesulfide (PPS),. PPS is a crystalline (crystallinity 55% -65%) of high rigidity white powder polymer, heat resistance and high (continuous use temperature of 240 ° C), mechanical strength, rigidity, flame retardancy, electrical properties, dimensional stability resin, abrasion resistance, excellent creep resistance, flame resistance. There are self-extinguishing. To UL94V-0 grade, high temperature, high humidity remains good electrical properties. Good fluidity, easy molding, molding, almost no shrinkage concave spots. Good affinity with various inorganic fillers. Enhancement modification can improve the mechanical properties and heat resistance (heat distortion temperature) of their physical and mechanical reinforcing materials glass fibers, carbon fibers, aramide fibers, metal fibers, etc., and glass fiber-based. Inorganic filler such as talc, kaolin, calcium carbonate, silica, molybdenum disulfide, glass fiber reinforced PPS having excellent thermal stability, abrasion resistance, creep resistance, in a wide range (temperature, humidity, frequency) has excellent mechanical properties and electrical properties, dielectric power is small, the number of low dielectric loss. High temperature, anti-corrosion coatings, coating at 180 ℃ under long-term use; connector for electrical and electronic industrial insulation barrier, terminals, switches; machinery and sticky secret machinery doing pumps, gears, piston rings, tank, leaves valve, watches parts, camera parts; automotive industry on the carburetor. Distributor parts, electrical and electronic group, and other parts, batch valve gas sensor primary pieces; appliance parts tape recorder structural components, products body diode, and a variety of parts; another is also used for aerospace, aviation industry, heat resistance excellent in its melting point exceeds 280 ° C, thermal deformation temperature is over 260 ° C, the temperature of 220-240 ° C and long-term use. In air at 700 ℃ degradation remains 40% by weight in the 1000 ° C an inert gas, the short-term heat resistance and long-term continuous use of the thermal stability were better than all of the current engineering plastics. Itself has a flame retardancy of the flame retardant polyphenylene sulfide can be achieved UL94-0 level, the oxygen index (LOI)> 57%. Polyphenylene sulfide own chemical structure, it has a good hard combustion properties, without the addition of flame retardants. Good mechanical properties extremely rigid, high surface hardness, Rockwell hardness> 100HR, tensile strength> 170MPa, bending strength> 220MPa, the notched impact strength> 16MPa, flexural modulus of 3.5 × 104, and has excellent creep resistance resistance and fatigue resistance. Chemical drug-resistant performance: yet found to be below 200 ℃ solvents dissolve polyphenylene sulfide extremely resistant to inorganic acids, bases and salts. Good dimensional stability, low molding shrinkage, is less than 0.0025%, the absorption rate is less than 0.05%, the coefficient of linear thermal expansion is also small. Still showed a good dimensional stability under high temperature, high humidity conditions. Therefore, in all aspects of machinery, chemicals, equipment, instrumentation and aviation, aerospace, ships with a wide range of applications. The electric superior performance polyphenylene sulfide in high temperature, high humidity, and high-frequency conditions still has excellent electrical properties, volume resistivity of 1 × 1016Ω.cm surface resistivity of 1 × 1015Ω, electrical strength> 18KV/mm. |
