Introduction and application of PPS resin for injection molding

Since the injection mold temperature must be maintained at 130 ~ 150℃, it is necessary to adjust the temperature of the mold with oil, or use the cylinder heater to keep warm. PPS resin polyphenylene sulfide price used to be more expensive, but recently due to mass production, has stabilized in a reasonable price range.

PPS outstanding performance: good heat resistance, thermal deformation temperature is generally greater than 260℃, can be used in the temperature range of 180~220℃, PPS is one of the best varieties of engineering plastics heat resistance; Corrosion resistance close to tetrafluoroethylene, chemical resistance second only to polytetrafluoroethylene; Excellent electrical performance; Excellent mechanical properties; Good flame retardant property.

PPS shortcomings: the price is too high, in the high temperature resistant material is the bottom price, but much higher than the general engineering plastics; Poor toughness, brittle; The medium viscosity is unstable.

The main uses of injection molding material PPS are as follows.

1. Automobile parts: electrical parts, engine peripheral parts and ECU shell

2. Electrical and electronic components: narrow pitch connector, aluminum electrolytic capacitor, CD pickup unit, optical pickup base, push button switch

3. Machinery industry: used as bearings, pumps, valves, pistons, precision gears, as well as photocopiers, cameras, computer parts, catheters, sprayers, nozzle, instrument parts, etc.

4. Others: kitchen faucet, mixing faucet, thermostat, etc

PPS resin is commonly used in surface-mounted electronic components requiring reflow soldering because the load deflection temperature is even higher than the melting point of the solder. Due to its good fluidity, it is easy to produce burrs during injection molding. PPS resin is a kind of super engineering plastic which can withstand up to 260℃ load deflection temperature. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
