NASBIS Insulating Sheets

Panasonic’s thermal management material, “NASBIS,” is a flexible heat insulating sheet composed of proprietary silica aerogel and fiber. Structured into nanoscale hollow particles, this highly porous sheet has a thermal conductivity of roughly 0.02 W/m·K, making it an excellent insulator. The thermal conductivity of NASBIS is lower than that of air, which means it provides high heat insulation. NASBIS sheets are extremely thin and flexible so they can be bent and used in narrow spaces. Applications include wearable devices, smartphones, and many other small electronic devices. NASBIS Insulating Sheets reduce the temperature of the case of a unit and give protection to thermally weak products from heat.

NASBIS sheets can provide various countermeasures against heat when combined with other thermal management products, especially Panasonic’s Pyrolytic Graphite Sheet or PGS. The properties of the resulting composite product restrain and reduce the temperature of hot spots of a heat source. As a result, the surface temperature of an electronic device can see great temperature reductions.
