PPS+GF offers high heat resistance and low moisture absorption, making it suitable for insulating fastening in connectors, terminals and power supply modules. Some material grades may provide long-term operating-temperature references around 200–220 °C; the actual limit must be confirmed against the supplier’s datasheet, part dimensions, load and operating environment.
Potential applications include ECU housings, sensor mounts, lighting assemblies and motor fastening points. Material compatibility should be verified for the actual temperature, fuels, oils, chemicals and fastening stresses involved.
PPS+GF is resistant to many acids, alkalis and organic solvents. It may be considered for non-metallic fastening in pumps, valves, agitators and piping systems after checking chemical concentration, temperature and mechanical load.
Glass-fibre reinforcement can increase stiffness, while low moisture absorption supports dimensional stability in insulating fasteners and jigs. Suitability for vacuum, clean-process or low-outgassing environments must be confirmed using test data for the exact material grade.
Because PPS+GF is comparatively rigid, suitable washers and controlled tightening torque are recommended to reduce stress concentration. For ultra-high-purity or low-particle processes, assess PFA, PTFE, PEEK or another validated material according to the actual application requirements.
The information above is provided for preliminary material selection only. Actual performance depends on the material grade, glass-fibre content, screw dimensions, tightening torque, mechanical load, chemical exposure and operating environment. Testing is required before final adoption.
