Glass-fibre reinforcement can improve stiffness, dimensional stability and creep resistance. PP+GF screws may be considered for RO/DI systems, chemical tanks, piping flanges and plating jigs in moderate-temperature environments. Compatibility must be verified for the actual chemical, concentration, temperature and mechanical load.
PP+GF may be considered for structural components and fixture fastening around wet-process equipment, where electrical insulation and low moisture absorption are required. For ultra-high-purity, low-particle or process-chamber applications, assess neat PP, PTFE, PFA or another validated material.
PP+GF screws may be considered for pumps, dosing systems, equipment housings and brackets. Glass-fibre reinforcement can help reduce material creep, but thermal cycling, vibration, chemical exposure and long-term fastening stress must be included in design verification.
PP+GF may be considered for switchboard accessories, terminal fastening and insulating spacers. Actual dielectric performance depends on the material grade, glass-fibre content, humidity, temperature and component geometry, and must be confirmed before final adoption.
Some PP+GF material grades may provide long-term operating-temperature references around 110–120 °C, but this does not apply to every grade or load condition. Use suitable flat washers, control tightening torque, avoid stress concentration and impact tightening, and verify performance against the material datasheet and actual load.
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.
