Thermo-Flex™ heat shield is a composite material manufactured to provide abrasion resistance, thermal insulation and physical containment of hoses or wiring. The combination of aluminium and silica produces a sleeving that is flexible, lightweight and strong. It can be slit for applications such as wiring looms without disconnecting the ends of the wires. Thermo-Flex can withstand temperatures up to 350C of radiant heat. Size: 1" x 36" Colour: Silver
