The continuous use temperature of ceramic fiber cloth can reach 1000 ℃, and the short-term use temperature can reach 1260 ℃; It has good resistance to acid and alkali corrosion and corrosion of molten metal such as aluminum and zinc; Good high-temperature strength and thermal insulation performance (see physical and chemical indicators); Ceramic fiber cloth, tape, packing and other series products with alkali-free glass fiber as reinforcing material have higher electrical insulation and high temperature electrical insulation than glass fiber;. It is non-toxic, harmless and odorless.

Ceramic fiber textiles contain about 15% of organic fibers. When used for the first time, the organic fibers in the products will gradually carbonize and become black with the rise of temperature, and there will be smoke. There may be flames in some places, which is normal and does not affect the use. As the temperature continues to rise, the product will gradually turn white again, the organic fiber has been completely carbonized, and the product is completely made of high-temperature resistant inorganic materials such as ceramic fiber.
