Silica Aerogel Felt
,Aerogel Felt Thermal Insulation
Aerogel Felt is a nano-composite material made from silica aerogel and reinforcing fibers. It offers extremely low thermal conductivity, low density, flexibility, and is environmentally safe. The product is waterproof, sound-absorbing, and shock-absorbing, serving as a high-performance, eco-friendly alternative to traditional insulation like PU, asbestos, or silicate fibers.
Soft and easy to cut, the blanket is fire-resistant, hydrophobic, and made from inorganic materials. It effectively replaces less efficient, non-environmental options such as fiberglass or asbestos-based insulation.
Applications include thermal insulation for industrial pipelines, tanks, furnaces, power plants, ships, automobiles, buried pipes, machinery, and various sectors including appliances, steel, and glass manufacturing.
