Polygram, a leading manufacturer of compounded polyphenylene sulfide (PPS) grades as part of the company’s growing range of polymers targeting significant performance leaps in electrification. 

Our OEMs and Tier 1 suppliers in automotive are constantly seeking ways to improve safety, reliability and sustainability without compromising system cost efficiency. 

We constantly work with our customers to find solutions to their challenges, leveraging the potential of our materials portfolio and our expertise to bring new innovations to life”.

As a high-voltage PPS material, Polyton® PPS combines a comparative tracking index (CTI) of 600 V for best-in-class electrical performance and electric thermal index (RTI) >175°C for superior heat resistance with UL94 V0 flammability ratings. This property provides a step-change towards safer and more reliable components in power electronics, such as housings and chip carriers. 

Polyton® PPS offers high mechanical strength and excellent flowability for 0.3 mm thin-wall components. It can make a significant contribution to miniaturization and package optimization. Target applications include bobbins for stators and insulators, where lower wall-thicknesses reduce the temperature of coils and facilitate reliable thermal management.
