DSM expands EV thermal management portfolio with new PPS grade

DSM Engineering Plastics has introduced a new PPS (polyphenylene sulfide) 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.

“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 130^◦C for 6,000–10,000 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:  

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