PC Insulation Flame-Retardant Sheet
- PC insulation flame-retardant sheet is a three-layer composite material based on PC polycarbonate, structured with acrylic foam structural adhesive, PC film, and high-tack cotton paper adhesive. It offers excellent electrical insulation, flame retardancy, temperature resistance, dimensional stability, and chemical corrosion resistance.
- Designed for energy storage systems, power batteries, NEV module barriers, and battery top cover insulation sheets, the material provides reliable insulation protection for various battery structural components.
- Custom anti-counterfeiting marks are available, with embossing height controlled within 0.005 mm to help prevent material substitution and ensure consistent product quality.
