PPS GF40 (40% glass fiber reinforced) is the standard high-performance PPS grade for structural applications. With 160 MPa tensile strength at 220°C continuous service, it offers the best performance-to-cost ratio of any glass-reinforced high-temperature polymer. PPS GF40 is the dominant material for automotive under-hood components (fuel system connectors, EGR valves, water pump impellers), electrical connectors requiring SMT solder reflow compatibility, and industrial pump housings exposed to hot chemicals.

Frequently Asked Questions
How does PPS GF40 compare to PEEK GF30?
PPS GF40 matches PEEK GF30 in tensile strength (160 MPa) but at 40-50% lower raw material cost. However, PPS has lower impact resistance (notched Izod ~80 J/m vs ~55 J/m for PEEK GF30) and a lower continuous service temperature (220°C vs 260°C). For applications below 200°C with chemical exposure, PPS GF40 is often the more economical choice.
