Marvite™ Insulation

Engi-Mat’s magnet wire insulation & motor resin – a proprietary family of products known as Marvite materials - offer dramatically improved thermal conductivity, enabling increased power density, increased efficiency, and longer life for motors, actuators and related products.

Marvite wire insulation satisfies NEMA MW1000, offers high thermal conductivity, and has a thermal index of 281 °C, while Marvite motor resin demonstrates high thermal conductivity. In solenoid coil tests, Marvite materials enabled 46% more power without increasing wire temperature (or 31% lower temperature rise at the same power).
