Aerogel Insulation Felt
The flexible felt material is made by combining aerogel and glass fiber using the sol-gel in-situ composite process. It is widely used in the fields of petrochemical industry, high-temperature steam pipelines, new energy vehicles and building exterior wall insulation. Aerogel insulation felt has been widely used in power plants, petrochemicals, steam pipelines, high-speed trains, fast-installed houses, and new energy vehicle industries due to its excellent thermal insulation performance and lightweight characteristics.
