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