Polymer Type
Thermoplastic
Advantages
Good combination of tensile strength and flexural modulus. Best electrical characteristics of PPS grades.
Disadvantages
Lowest oxygen index of PPS grades. Incorporation of glass can cause anisotropy in mouldings.
Applications
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.
