C11S-Y Pre-Oxidized Fiber Aerogel Insulation Sheet
Category: Thermal Insulation Range
Product Details
The C11S‑Y preoxidized fiber aerogel insulation sheet is manufactured by combining a preoxidized fiber felt with silica aerogel using supercritical drying, resulting in a lightweight porous material with a three-dimensional network of nanoscale pores. It is applied either through membrane encapsulation or adhesive coating. At room temperature, its thermal conductivity is as low as 0.025 W/(m·K) or less.
Product features: high‑efficiency thermal insulation, high compression ratio, flexible packaging options, and suitability for a wide range of applications.
