Pre-oxidized silk aerogel felt is a high-performance thermal insulation material that combines silica aerogel with pre-oxidized fiber, offering exceptional fire resistance, low thermal conductivity, and flexibility. Its thin, lightweight structure makes it ideal for applications where space is limited, such as new energy vehicle battery insulation, electrical equipment, rail transit systems, and small pipelines. With excellent thermal stability, softness, and tear resistance, this material effectively prevents heat transfer, delays fire spread, and enhances overall safety in modern industrial environments.
