PPS GF40 Pellets Product Description
40% glass fiber reinforced polyphenylene sulfide pellets (PPS-GF40) are high-performance engineering plastic pellets produced by compounding PPS resin with 40% chopped glass fiber via twin-screw extrusion and pelletizing. The addition of glass fiber substantially overcomes the inherent weaknesses of neat PPS, delivering a tensile strength of 205 MPa, a flexural modulus of 13.8GPa, a heat deflection temperature (1.8 MPa) of 260–270°C, and a continuous use temperature of 200–240°C, while maintaining very low water absorption, a low coefficient of linear thermal expansion and excellent dimensional stability.
Combined with its retardancy , resistance to acids, alkalis and organic solvents, and outstanding electrical insulation, PPS-GF40 is an ideal choice for replacing metal with plastic.
The material is processed primarily by injection molding (barrel temperature 290–340°C, mold temperature 130–160°C) and is widely used in automotive under-the-hood components and new energy vehicle battery/motor/electronic control parts, electrical and electronic connectors and relay housings, chemical pumps and valves, and precision structural parts.

|PPS GF40 Pellets Application
40% glass fiber significantly enhances the mechanical strength of Polyphenylene sulfide material. Moreover, it can still maintain rigidity and load-bearing capacity at high temperatures, while retaining the original corrosion resistance and hydrolysis resistance of PPS material. Therefore, PPS GF40 particles are suitable for use in injection molding for components that are to be used in high-temperature, corrosive and humid environments for a long time.

PPS GF40 pellets Testing Quality
For each batch, we strictly control the content of PPS fiberglass to ensure it meets the performance standards stated in the data sheet that we Decla. When the glass fiber content is determined to be 40%, we will test whether its mechanical properties meet the standards. Secondly, we will measure the density of PPS GF40 to ensure that it reaches 1.67g/cm3
