Square Battery Materials

Insulation and Heat Dissipating Materials for Thermal Design Requirements

Offering high strength and energy density, square batteries incorporate thermally insulating and heat dissipating materials. Iwatani handles a wide range of sheets, potting materials, and adhesives for use with these thermally insulating and heat dissipating materials. We offer materials that meet thermal design requirements for vehicle and consumer batteries.
