Introduction
Nanoporous aerogel insulation felt is a composite insulation material composed of silica aerogel and glass fiber needle felt. The product uses silicone as a precursor, forms a gel through hydrolysis and polycondensation, and is compounded with glass fiber needle felt when the gel is formed, and then is obtained through supercritical extraction. It solves the problem of brittleness of pure aerogel materials and has the advantages of convenient construction, good thermal insulation performance and high stability.
