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.

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.

Non-woven fabrics are increasingly being used in the automotive industry due to their excellent performance, sustainability, and cost-effectiveness. These materials are applied in various car components such as soundproofing systems, air filtration, and seat linings, significantly enhancing comfort, noise reduction, and overall vehicle performance. Non-woven fabrics also offer significant environmental benefits, such as recyclability and waste reduction, making them an ideal alternative to traditional materials like foam and leather. As car manufacturers prioritize eco-friendly solutions, the demand for non-woven fabrics is expected to grow, paving the way for further innovation and adoption in the automotive sector. This article explores the role of non-woven fabrics in automotive manufacturing, their benefits, and future market trends.
