As the “heart” of new energy vehicles, drive motors demand automotive insulation materials that combine high thermal conductivity, partial discharge resistance, and chemical compatibility with cooling media. Permanent magnetization, high-speed operation, oil-cooled flat wire, and 800V high-voltage systems have continuously raised the bar for vehicle insulation performance.

Sui On Insulating provides a complete range of proven insulation for automotive drive systems — from Nomex® aramid paper and polyimide films for thermal and mechanical protection, to SOFLEX® NSN composite paper and PEEK materials for 800V high-voltage partial discharge resistance and ATF chemical compatibility. As a trusted supplier of automotive insulation solutions, we combine broad product coverage with rapid new solution development to support the continuous innovation of EV motor technology.
