One of the major growth drivers for Polyphenylene Sulfide is the automotive sector’s increasing demand for under-hood, thermal-resistant components. PPS is used in coolant system parts, fuel system components, thermostat housings, and electrical connectors due to its ability to withstand continuous service temperatures well over 200 °C and its chemical resistance to oils and automotive fluids. 

In addition, the electrical & electronics industry values PPS for its dielectric properties and dimensional stability, making it useful in parts such as connectors, switches, housing for high-temperature components, and other high-end assemblies. The dual application across automotive and E&E strengthens the market foundations for PPS.
