Polyphenylene Sulphide - PPS 40% Glass Fibre Reinforced

Polymer Type



Good combination of tensile strength and flexural modulus. Best electrical characteristics of PPS grades.


Lowest oxygen index of PPS grades. Incorporation of glass can cause anisotropy in mouldings.


Coil bobbins, terminal blocks, connectors, relay components electric motor housings. Automotive headlamp bulb holders and boxes for electronic components where resistance to petrol, oil and hydraulic fluid is important.

Exhaust gas emission control valves. Pumps, valves and taps for chemical and petrochemical industries. Precision mechanical parts.
