Heat treated fiberglass sleeving is made of alkali-free fiberglass yarn braided into pipes and then bonded with small amount of Silane binder after high temperature dewaxing and fixed grain impregnation. The heat shield fiberglass tubing is mainly applied to insulate and heat equipment, such as motor, engine, plug wire, fuel lines, decorative light, etc.

Aluminum foil coated fiberglass sleeve special designed by laminating an aluminized metallic heat shield to a layer of strong and tight braided fiberglass yarn. A special manufacturing process permits the sleeve to boast a virtually seamless and non fraying construction. This aluminized fiberglass sleeve reflects more than 95% of the radiant energy that hits its surface, keeping the underlying cables, hoses and wires cool.
