DuPont’s BETATECH thermal interface material (TIM) has been specified by Renault for supply to its Maubeuge and Douai production facilities in northern France. A multi-year technical partnership with the Alpine F1 team was also announced.

BETATECH helps manage and control heat from higher-density batteries during both charging and operation. This is accomplished by maintaining thermal conductivity through good contact with no gaps between the battery cells and the cooling plate over a wide operating temperature range. The coating is available as a 1K or 2K dispensable thermal-conductive polyurethane product applied between the battery module and heatsink. 

“This qualification reinforces our longstanding relationship with Renault,” said Randy Stone, President of DuPont Mobility and Materials. “Along with ongoing collaboration on the vehicle manufacturing side, our technical development partnership with the Alpine F1 Team will enable us to test innovation and technical advances under the harsh environment of racing so that we can anticipate and address the toughest challenges for HEV/EV development.”
