High-Temperature Fabrics for 1500–1800°C
For continuous use in air at 1500–1800°C, ceramic fiber fabric (alumina-silicate based) is the only practical choice. It can withstand up to 1400–1600°C continuously, with 1800°C as a short-term peak limit.

Carbon fiber fabric is not suitable for air applications. It oxidizes and burns above 400°C in oxygen. Its high-temperature rating (1500–2000°C) applies only to inert atmospheres or vacuum.

High-silica fiber fabric softens at 1700°C but cannot be used continuously above 1200°C. Above this temperature, it becomes brittle and loses strength.

Suntex Composite, a leading manufacturer of high-temperature industrial textiles, can supply various types of silica fabric.

Thanks to its unique understanding of coating technology, Suntex Composite has significantly enhanced the performance of silica fabric through a series of treatments. This has resulted in improved abrasion resistance, higher strength, and easier cutting of silica fabric.

Basalt fiber fabric is limited to 700–800°C continuously, with brief peaks up to 1200°C. It cannot withstand 1500°C in practice.

Conclusion: For genuine 1500–1800°C fire protection in normal air, use high-purity ceramic fiber fabric. Do not use carbon, high-silica, or basalt fabrics for this temperature range.
