Fiberfrax® Wicking Textiles are a high-temperature twisted roving made from refractory ceramic fibers and organic carrier fibers with a temperature grade of 1260°C (2300°F). It possesses the same thermal and chemical properties common to all Fiberfrax forms. It is typically used in applications that do not demand high tensile strength or compression resistance.
These products are dense, resilient, ceramic fiber materials, widely used for a broad variety of high-temperature gasketing, packing, and sealing applications.
Fiberfrax textiles have excellent resistance to thermal shock, corrosive attack and breakdown due to mechanical vibration and stress. They also exhibit excellent chemical stability, resisting attack from most corrosive agents. Exceptions are hydrofluoric and phosphoric acids and concentrated alkalies. Fiberfrax textiles also resist oxidation and reduction.
