THERMOGLASS SLEEVE™ BRAIDED
FIBERGLASS SLEEVINGview specs
Thermoglass is a braided fiberglass material employed to protect cables from abrasive wear. It is a pliable material that can be sleeved over long lengths and the braided construction allows it to fit a wide range of diameters. Thermoglass can withstand long-term exposure to temperatures up to 1,000°F.
T-Glass Sleeve is ideal for covering induction furnace, and arc furnace power cables.

KEVLAR SLEEVINGview specs
Kevlar is a polymer material consisting of aramid fibers that form a crystalline arrangement during the manufacturing process, which creates a material that is highly resistant to abrasion. Kevlar has excellent thermal stability and can sustain long-term use at temperatures up to 160°C / 320°F without significant strength loss. The braided construction allows Kevlar to be flexible, thus making it well-suited to protect wires, hoses, and cables from extremely abrasive conditions.

POWER JACKET™ SLEEVINGview specs
Power Jacket is a knitted glass fiber that is saturated with a silicone rubber that helps keep the fibers intact, and to maintain their insulative properties. Power Jacket is capable of withstanding temperatures of 500°F on a continuous basis, with exposure to 2,000°F for 8-10 minutes, and 3,000°F on a brief intermittent basis. The knitted construction allows Power Jacket to accommodate a range of diameters, while bending/flexing. The material is also resistant to oils, fuels, and heat transfer fluids. Power Sleeve is best utilized on power cables, pendant controls, hydraulic lines, or any other cable that has exposure to molten metal splash. Power Sleeve is available from ¼” to 6” I.D. in 100’ lengths. This product is in compliance with SAE Aerospace standard 1072D.

We can provide Power Jacket with a customized Velcro® type seam to facilitate installation/removal. Please contact I²r for details.

TEFLON® SHEET DATAview specs
Teflon is a transparent, thermoplastic film material. Teflon can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metallized, laminated, and is an excellent hot-melt adhesive. Teflon is chemically inert and solvent resistant to virtually all chemicals, except molten alkali metals, gaseous fluorine, and certain complex halogenated compounds. Teflon’s array of fabrication possibilities, along with its important properties, allow for a unique combination of capabilities not available in any other plastic film.
