AEROGEL BLANKET

Prodution

Aerogel is the lightest solid material. It exhibits unique properties in mechanics, acoustics, thermics, optics, etc., and is used in many fields such as aerospace, military, medicine, building materials, electronics, metallurgy.

Aerogel is the best thermal insulation material with extremely low density, "endless" hollow walls can minimize thermal radiation. Aerogel can achieve a thermal insulation effect that other materials cannot match. The thermal conductivity coefficient of aerogel is lower than that of air (at normal atmospheric pressure): below 0.018 w/mk. For comparison: kt air = 0.025 w/mk.

AEROGEL BLANKET
when ethyl silicate is used as a source of silicon obtained by the sol-gel method, small particles of silicic acid sol are formed into a polymer spatial network structure, which turns into a nanoporous structure as a result of aging and can be completely hydrophobic (waterproof) after chemical modification. Then supercritical drying with carbon dioxide is used to replace the liquid in the spatial structure with gas. This air-containing porous structure is an inorganic silica aerogel. The thermal conductivity of aerogel insulation materials at room temperature is below 0.018 w/(m·k), and they have excellent insulating characteristics at high temperatures.
