Ceramic Insulation and Textiles

Ceramic insulation and textiles are fibrous refractories or thermal insulation products that consist of ceramic fibers in bulk, cloth, batting, paper or rope forms. There are many types of products. Blankets consist of thick layers of woven or nonwoven fabric sheets. Woven materials are used for composite tooling and the formation of multi-dimensional structures. Nonwoven materials are shaped into mats of randomly oriented fibers. Ceramic fabric or cloth is made by weaving, knitting, braiding, or extrusion. Materials can also be needlepunched or formed from slurries (wet laid). Fibrous monofilaments or single-fiber threads are often used in reinforcement applications. Multi-fiber threads are used in sewing or stitching. Roving is made of tows, untwisted bundles of continuous filaments. Yarn is made of continuous, plied strands of natural or synthetic fibers. Heat-insulating rope is used to provide a thermal seal around doors or other openings in furnace walls. Sleeves or wraps are flexible, fibrous refractories for insulating pipes, tubes, ducts and other process components. Common types of ceramic insulation and textiles include woven ribbons, webbing, strapping, and tape.
