Electric Vehicle (EV) Motor Potting Compounds

Quality Potting Resins – Essential for EV Motor Protection

Impregnating motors with thermal management materials

Custom EV (electronic vehicle) motor potting/casting compounds

Epic Resins is on the leading edge of formulating UL-recognized epoxies and polyurethanes with strong dielectric properties—perfect for optimizing EV motor performance. Manufacturers benefit from using resin products like these, which lower the costs of components and lead to wider adoption of the technology.

Thermally conductive encapsulants for lower motor operating temp

A common maxim in the motor industry is that every ten degrees of reduced operating temperature corresponds with a doubling of engine life. The still-developing electric vehicle motor industry places a premium on a motor’s ability to carry a high current without overheating. Potting or encapsulation compounds can lower the operating temperature of electric motors, resulting in higher power output, longer engine life, and better reliability.
