SUPHIP® Nano Composite Insulation Material
Advanced thermal barrier for EV and energy storage battery safety.
Combines ultra-fine nano insulation powder with inorganic fibers to block heat transfer and prevent thermal runaway.
Innovative Inorganic Fiber Nanocomposite for High-Temperature Thermal Protection
SUPHIP® is an inorganic fiber nanocomposite insulation material developed as an innovative thermal barrier for power and energy storage battery systems. It consists of ultra-fine porous nano insulation powder and special inorganic fibers, designed to isolate heat in three dimensions — conduction, convection, and radiation.
Featuring low thermal conductivity even at high temperatures, SUPHIP® effectively prevents heat diffusion during battery thermal runaway events, significantly improving safety and efficiency. The material offers high-cost savings compared to aerogel, with comparable performance, improved consistency, and no fiber residue impurities.
With excellent flame resistance (over 10 minutes at 1000 °C), high compressive strength (>2 MPa), and compliance with RoHS, REACH, and ELV directives, SUPHIP® is ideal for long-term, high-temperature insulation and protection in EV, energy storage, and aerospace applications.
NAGASE supplies the SUPHIP® insulation series with full technical support, customization options, and reliable logistics services.
