Have you ever imagined a type of fabric that can endure prolonged exposure to 1000°C and only softens at 1700°C? This isn’t science fiction—it’s high-silica fiber cloth, a cutting-edge fireproof material widely used in aerospace, firefighting, and industrial applications.
Today, we’ll uncover the secrets behind this "unburnable" fabric, explore how it protects lives, and take a closer look at its birthplace—Zhenjiang, China—where advanced manufacturing meets innovation.
1. High-Silica Fiber Cloth: The Ultimate Fireproof Shield
High-silica fiber cloth is an inorganic fire-resistant fabric with a 96% silicon dioxide (SiO₂) content, giving it extraordinary heat resistance:
Long-term use at 1000°C (ordinary fabrics burn at 300°C)
Short-term resistance up to 1200°C (withstands sudden thermal shocks)
Softening point at 1700°C (close to the melting point of steel!)
Beyond heat resistance, it boasts other superpowers:
✅ Non-combustible & non-melting—maintains structural integrity in flames
✅ Corrosion-resistant—immune to acids and alkalis
✅ Superior insulation—low thermal conductivity blocks heat transfer
✅ Flexible & workable—can be sewn, laminated, or coated
