Panasonic launches industry-thinnest aerogel thermal insulation solution



NASBIS is made of a material called aerogel

Panasonic Automotive & Industrial Systems Europe has recently unveiled a thermal insulation sheet which is the thinnest insulation solution currently available on the market. The NASBIS (Nano Silica Balloon Insulation Sheet) high-performance thermal insulation sheet comes with a thickness of 50μm, 100 μm, 500 μm, or 1000 μm and an ultra low thermal conductivity of 0.018 to 0.024 W/mK. This very low thermal conductivity of convection is achieved thanks to a pore diameter which is smaller than mean free path of air (68nm).

NASBIS is made of aerogel. This is a synthetic porous material derived from a gel, but in which the normal liquid component of the gel has been replaced with gas. In addition to its ultra low thermal conductivity, aerogel benefits from a low sound propagation of 120m/s, low bulk density of 0.050 up to 0.250g/cm³, high transparency of 90% up to 94% at 10mmt, a refractive index like air of 1.015 up to 1.055, as well as high porosity of 90% up to 98%.

According to Satoshi Endo, Product Manager, Thermal Solutions & Ceramic Devices at Panasonic, “The flexibility and fantastic heat insulation performance of the ultra thin NASBIS thermal insulation sheet make it the ideal solution for applications where it is important to cancel a heat spot in a narrow space, e.g. in mobile phones”.
