DuPont™ Kapton® MT+ based Slot Liner Solution Improves Thermal Management and Efficiency in High-Voltage E-Motors
- DuPont's collaboration with a leading provider of mobility system solutions and an electrical insulation system provider has resulted in the successful implementation of Kapton® MT+ based NKN slot liners in 800V e-motors for a high-end EV manufacturer. This will likely lead to increased demand for DuPont's slot liners from other EV OEMs as well, as they aim to build more advanced e-motor offerings. The high thermal conductivity and electrical insulation properties of the slot liners make them ideal for preventing failures in critical eMotor systems and enabling superior heat dissipation in compact e-motors. The Kapton® MT+ film also provides superior voltage endurance, ensuring longer life of e-motors at high voltages, such as 800V+.

Kapton® MT+ Delivers High Thermal Conductivity for Cooler-Running, More Efficient Motors in Next-Generation Electric Vehicles
DuPont collaborated with an e-motor developer and a leading electrical insulation system provider to develop a slot-liner solution. Slot liners protect the copper wires in the e-motor from the outer steel wall, dissipating heat to the outside and enabling the motor to operate efficiently at a cooler temperature. In addition, the NKN laminate sandwiches Kapton® MT+ film between two layers of DuPont™ Nomex® paper for electrical insulation, making it ideally suited for this application.
"With global demand for EVs continuing to accelerate, e-motors must run as safely as possible with the highest energy efficiency," said Greg Randisi, Automotive Global Marketing & Business Development Leader with DuPont Interconnect Solutions. "This collaborative solution signals a significant win for our Kapton® MT+ based high thermal conductivity NKN slot liners that we plan to make available to other EV OEMs as companies build out their more advanced e-motor offerings."
Failure in the field is not an option. Just as designers of high-speed traction motors and other high-performing motors have trusted in DuPont solutions for decades, EV design engineers can rely on the Kapton® MT+ based NKN slot liner solution to prevent failures in critical eMotor systems. The DuPont™ Kapton® MT+ based slot liners can be proliferated to other EV OEMs as part of motor providers' e-motor/powertrain offerings, as their high thermal performance enables OEMs to make more compact, better-performing e-motors with superior heat dissipation. Additionally, Kapton® MT+ provides superior voltage endurance, enabling longer life of e-motors at high voltages, 800V+. DuPont offers a variety of thicknesses of Kapton® MT+ film that can effectively dissipate heat in larger e-motors such as those used in trucks and novel aircraft.
