High-Temperature Fabric

A high-temperature fabric is a technical textile capable of withstanding very high temperatures, often up to 500°C or even higher (up to 1600°C depending on the material). These fabrics are made from heat-resistant fibers such as fiberglass, aramid, ceramic, or silicon and are sometimes coated with materials like silicone, Teflon, or others to enhance their heat resistance, flexibility, and durability. They are primarily used in applications that require protection from extreme heat, such as in industry (metal production, welding, petrochemicals), aerospace, and fire safety. They provide thermal insulation, protection against flames and heat, and resist mechanical stress as well as chemical exposure. Typical applications include heat-protective blankets, heat-resistant curtains, protective clothing, insulation wraps, and seals. In addition to heat resistance, they often have properties like low thermal conductivity, non-flammability, and mechanical strength.

To further improve performance, these fabrics can be treated with special coatings such as silicone, Teflon (PTFE), graphite, and vermiculite. Silicone coatings offer excellent thermal stability, flexibility, and protection against chemical and abrasive influences. Teflon coatings provide superior chemical resistance and non-stick properties, ideal for harsh environments. Graphite coatings enhance heat dissipation and reduce friction, while vermiculite increases thermal insulation and provides added protection against flames, sparks, and splashes, making it ideal for welding and industrial heat applications. These coatings extend fabric lifespan and enhance safety and functionality in demanding conditions.
