Silica Ultra-Sleeve


TPC Wire & Cable Corp. now offers excellent flame and heat protection with its Thermo-Trex® Silica Ultra-Sleeve™ for use in steel mills, manufacturing plants, foundries, glass factories and welding & cutting shops. In an effort to add to the variety of high temperature accessories available to their customers and to offer an alternative to the Ceramic Ultra-Sleeve™, TPC has added the Silica Ultra-Sleeve™ to its Thermo-Trex® line of high heat resistant products. Thermo-Trex® Silica Ultra-Sleeve™ uses silica fiber that is 96 percent pure, which is a better option to asbestos or ceramic sleeves as none of the negative health effects often associated with those materials exists. The sleeve provides short term temperature resistance up to 3,000°F (1,650°C) while offering outstanding flame resistance, flexibility and tensile strength. 

Thermo-Trex® Silica Ultra-Sleeve™ is a braided silica fiber woven into a sleeve that slips over cables running through areas where extreme heat or flame is present or nearby. The sleeve offers protection from continuous operating temperatures up to 1800˚F (982°C). Because it also protects from water, grease and hydraulic oils, the Thermo-Trex® Silica Ultra-Sleeve™ is perfect for cable covers, cable tray protection, welding cable protection, hose protection and protection from abrasion. TPC’s customers will find this high temperature sleeving works well in applications such as primary metals operations, refineries, blasting, cast and electric arc furnaces, robotic weld cells, utility power stations, plastic molding plants, fire protection equipment and in the food & beverage and auto industries. Additional inside diameters up to four inches are available upon request.
