SABIC launches PPS compounds for 800 V EV inverter power modules and fast chargers

SABIC introduced two polyphenylene sulfide compound grades, LNP THERMOCOMP OFM76XXP and OFM76EXP, designed to insulate high voltage power modules in 800 V and higher traction inverters and fast chargers. The compounds carry a CTI rating of PLC 0, retain 90% of strength and insulation after 1,000 hours at 200°C, and meet UL94 V0 flame retardancy at 0.4 mm wall thickness. SABIC states the materials offer better dimensional stability and thermal shock resistance than PBT and PPA alternatives, supporting thinner, lighter components for densely packaged 800 V power electronics.

Why it matters: The compounds address material stress in 800 V charging infrastructure and inverter systems, where higher voltages and compact designs demand improved insulation performance. Specifiers procuring fast chargers or power electronics can evaluate these grades for modules requiring enhanced thermal endurance and tracking resistance.
