Article Summary: Pre-oxidized fiber is a high-performance flame retardant and heat-resistant material widely used in protective clothing, welding blankets, automotive brake pads, and aerospace insulation. Produced from PAN precursor fibers under 200–300°C, it forms a stable ladder structure that prevents melting and ignition. Dongguan Yuexin Industrial Co., Ltd. provides durable pre-oxidized fiber nonwoven and felt products offering excellent thermal stability, chemical resistance, and flexibility. Ideal for high-temperature industrial and safety applications, Yuexin’s pre-oxidized fibers ensure reliable performance and compliance with international fire protection standards.

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.
