DSM PPS grade DSM Engineering Plastics has introduced a new PPS (polyphenylene sulphide) grade to optimize the performance of electric vehicle thermal management systems. Xytron™ G4080HR is a 40 percent glass-reinforced PPS engineered for heat aging performance, hydrolysis resistance, dimensional stability, chemical resistance at elevated temperatures and intrinsic flame retardancy.

Enhance the Performance of Electric Vehicles


“As our customers work to enhance the performance of electric vehicles through lightweighting, it is essential for us to design lightweight materials able to withstand the increased heat and prolonged chemical exposure requirements of EV thermal management systems,” said Lu Zhang, global business line director, DSM Engineering Plastics.

Xytron™ G4080HR


Since Xytron™ G4080HR is specifically formulated for typical EV thermal management system lifecycles, it maintains its strength at continuous operating temperatures exceeding 130°C for 6,000 to 10,000 hours. In a recent 3,000 hour 135◦C water-glycol fluid test versus a comparable competitor grade, Xytron™ G4080HR delivered 114 percent higher tensile strength and 63 percent higher elongation at break.

The unique combination of resistance to heat, moisture and chemicals make the Xytron™ family of materials a preferred solution for applications in many industries, including:
  • Automotive: powertrain parts, turbo systems, thermal management, automotive electronics and lighting
  • Electrical and Electronics: connectors, structural parts, e-motors, bobbins, switches and sensors
  • Industrial: water management, compressors, heat pumps, appliances, small engines, aerospace, oil and gas, pneumatics and hydraulics

Xytron™ G4080HR is now available for sale worldwide. The material is manufactured by DSM NHU Engineering Plastics (Zhejiang) Co. Ltd., a joint venture of Royal DSM and specialty chemicals producer Zhejiang NHU Special Materials Co., Ltd. (NHU).
