Polyphenylene Sulfide (PPS) Plastics

his resin is characterized by excellent high-temperature performance, inherent flame retardance, and good chemical resistance. The crystalline structural of PPS plastic is best developed at high mold temperatures. Most PPS plastic is sold in the form of filled and reinforced compounds for injection molding. Because of its heat and flame resistance, the plastic has been used to replace thermoset phenolics in electrical/electronics applications. PPS will withstand contact with metals at temperatures up to 500 degrees F, and in the electrical / electronics market, its biggest use is in molding connectors and sockets.

Applications: Molded surface-mounted components, circuit boards, industrial pump housing, valves, and downhold parts for the drilling industry, as well as appliance parts that must withstand high temperatures such as heaters, dryers, microwave ovens, and irons.
