DSM expands electric vehicle thermal management portfolio with new PPS grade

Parsippany NJ, US, 18 Apr 2019 17:00 CEST

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, announces its Engineering Plastics business has introduced a new PPS (polyphenylene sulphide) grade to optimize the performance of electric vehicle (EV) thermal management systems. Xytron™ G4080HR is a 40% glass-reinforced PPS engineered for heat aging performance, hydrolysis resistance, dimensional stability, chemical resistance at elevated temperatures and intrinsic flame retardancy.  

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.

Since Xytron G4080HR is specifically formulated for typical EV thermal management system lifecycles, it maintains its strength at continuous operating temperatures exceeding 130C for 6,000 to 10,000 hours. In a recent 3,000 hour 135C water-glycol fluid test versus a comparable competitor grade, Xytron G4080HR delivered 114% higher tensile strength and 63% 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 Royal DSM and specialty chemicals producer Zhejiang NHU Special Materials Co., Ltd. (NHU) joint venture. To learn more, visit dsm.com/xytron.
