C11S-S Ceramic Fiber Aerogel Insulation Sheet

The C11S‑S ceramic fiber aerogel insulation sheet is manufactured by combining a ceramic fiber felt with silica aerogel via supercritical drying, yielding a lightweight porous material with a three-dimensional network of nanoscale pores. It is applied using membrane‑type encapsulation or adhesive coating. At room temperature, its thermal conductivity is as low as 0.025 W/(m·K) or less.
