High Temperature Ceramic Fiber Rope Gasket - CeraTex Square Braided 1" x 25ft Rope Seal for Boiler, Furnace, Oven, Kiln & Casting | Heat Resistant Insulation for Industrial & DIY Projects

Ceramic Fiber Textiles are manufactured from alumina-silica ceramic fiber consisting of 47% Alumina, and 53% Silica. The textiles are free of asbestos and crystalline silica, also known as free silica. The material is typically used up to 2300F (1260C). Textile products do contain approximately 15% organic carriers which aid in formation and manufacturing. These organics do burn out at 750F (400C). Textile products can also contain reinforcement insert materials of Inconel wire or continuous fiberglass filament to increase handling strength during installation and to enhance fiber durability. Inconel reinforcement has a temperature rating of 2000F (1093C) and fiberglass reinforcement has a temperature rating of 1200F (649C). Round and Square Ceramic Fiber Braid are manufactured by over-braiding around a core of ceramic fiber to achieve maximum resistance to mechanical abuse with a density range of 33-36 PCF. In addition to its superior strength, round and square braids also exhibit minimal unraveling when cut.
