Ceramic Fiber Textiles
Ceramic fiber textiles are high performance thermal textiles made of high quality ceramic fiber. The textiles range is composed of yarn, cloth, tape, rope, braided packing, sleeves, etc.
They are reinforced with E-glass fiber or chrome-nickel steel wire. E-glass fiber reinforcement is used where metal is undesirable, especially when using the textiles as a dielectric, while the steel wire reinforcement provides maximum strength at elevated temperatures. In applications where the tensile strength is important, temperature limits of inserted materials should be considered.
Ceramic fiber textiles contain carrier fiber to facilitate the carding process. The textiles normally contain 16-20% rayon fiber which will burn out at high temperature, but has no effect on the properties of the products.
