Polyphenylene sulfide (PPS)
Description (definition)
Polyphenylene sulphide (PPS) is a high-performance thermoplastic known for its excellent chemical resistance, heat resistance and mechanical stability. PPS remains dimensionally stable even at temperatures of up to 240 °C and offers low water absorption. Due to its exceptional properties, PPS is used in the automotive, electrical and household appliance industries, where reliability under extreme conditions is crucial.
An example
A typical example is the use of PPS in the automotive industry for pump housings or valves. Thanks to its chemical resistance and high temperature resistance, PPS is ideal for these applications.
What advantages does PPS offer in the electronics industry?
PPS is used in electronics for connectors, switch housings and insulators. It offers excellent electrical insulation, is flame-retardant and retains its dimensional stability even at high operating temperatures.
Is PPS recyclable?
PPS is recyclable, but recycling requires special processes due to the material’s high temperature resistance and strength. Recycled PPS is often used in applications where slight deviations in material properties are tolerable, such as in structural components.
What mechanical properties make PPS unique?
PPS is characterized by high strength, rigidity and wear resistance. These properties enable it to be used in precision components that have to withstand high mechanical loads and thermal stresses.
