PPS plastic (polyphenylene sulfide) English name:PolyphenylenesulphideSpecific gravity: 1.36 g / cubic centimeter molding shrinkage: 0.7% molding temperature: 300-330. It is a kind of thermoplastic engineering plastics with excellent comprehensive properties, which is characterized by high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. Linear PPS is crosslinked at 350 DEG C and is thermosetting plastic. The branched structure PPS is thermoplastic. PPS is a white powder with an average molecular weight of 0.4-0.5 million and a density of 1.3-1.8 grams per cubic centimeter, and PPS has very excellent thermal properties. Add the thermal performance of glass fiber reinforced after the higher, at 232 degrees Celsius by 5000h after heat aging, such as glass fiber, carbon fiber and filler to enhance the mechanical properties of the modified PPS can maintain high mechanical properties and dimensional stability in the long-term work load and thermal load. It can be used in high temperature stress environment. Applied in: (1): PPS for automobile industry automobile industry accounted for about 45%, mainly used in automobile function parts, ignition, heater, thermostat, lamp holder, such as bearings; can replace the metal production exhaust valve and circulating water pump impeller, pneumatic signal regulator etc..
(2) mechanical industry: for shell, structural parts, wear-resistant parts and sealing materials, specifically pumps, valves, bearings, bearings, stents, piston rings and gears.
(3) textile fiber: used for special industrial dust removal equipment.
(4) film / insulating paper: used for motor insulation.
