DuPont Launches a Resin Patented for Use in Coolant Purification Systems for E-Mobility Applications

Designed specifically for the transportation sector,  DuPont™ AmberLite™ EV2X resin helps extend the lifetime of an electric vehicle’s glycol coolant and ion exchange filter


WILMINGTON, Del., Feb. 15, 2024  – DuPont today launched its DuPont™ AmberLite™ EV2X resin, a high-performing glycol-purification solution for e-mobility. This new solution helps extend the lifetime of electric vehicle (EV) coolant while reducing glycol maintenance requirements by offering enhanced thermal stability and excellent operating characteristics compared to standard ion exchange resins currently on the market.

“Consumer demand for increased range, faster charging, larger vehicles, and more energy-dense batteries is increasing temperatures within EVs, creating new challenges for vehicle manufacturers. Many manufacturers are turning from air cooling to liquid cooling systems that use glycol coolant to manage these higher temperatures. Glycol coolants are typically more efficient, and demonstrate more flexible and consistent performance versus other thermal management systems," explains Noel Carr, DuPont marketing manager in support of e-mobility solutions. “However, high operating temperatures can lead to degration of  parts, components and coolants, resulting in short circuits and shutdowns of electric and hydrogen vehicles”

Unlike internal combustion (ICE) vehicles, EVs have to manage conductivity within their systems. The degradation of the glycol coolant and other components housed within the thermal management system, releases impurities into the cooling loop, increasing the levels of conductivity. To prevent this, hydrogen fuel cell and battery vehicle manufacturers can install an ion exchange filter comprised of ion exchange resins that can withstand the extreme temperatures and operating conditions of the system.

DuPont™ AmberLite™ EV2X resin’s purification functionality is critical, helping to extend the life of the glycol coolant, coolant loop components, and the ion exchange filter. This optimized resin has been tested and validated under extreme conditions, up to 105°C for over 1,000 hours, demonstrating exceptional thermal stability and operating characteristics compared to standard ion exchange resins.

“Due to the high operating temperatures within coolant loops it is inevitable that degradation of components and coolant will occur; negatively impacting the performance of the glycol coolant and increasing conductivity throughout the system,” continued Carr. “With minimal loss in operational consistency after hundreds of hours at high temperatures, DuPont’s new solution can give suppliers and manufacturers greater confidence in the performance and longevity of coolant loops specified for fuel cell and lithium battery EVs.”

DuPont solutions are helping the electrification of the transportation industry with market-leading expertise in engineered materials and advanced adhesive technologies. From application development to technical support, DuPont is ready to support your greatest e-mobility challenges.
