HG/HG Vitreous Silica Heavy Build Fiber

HG/HG Vitreous Silica Heavy Build Fiber

Vitreous Silica fiber designed for extreme temperature applications. Vitreous Silica fiber in this design is braided with thicker insulation on the individual conductors and the jacket giving a continuous temperature rating up to 1800 Degrees F (982 Degrees C). The vitreous silica fiber is flexible throughout the extended temperature range but is not recommended for application that are highly abrasive in high temperatures. The high temperature limit of Vitreous Silica allows it to be used in areas where temperature is higher than the upper limit of fiberglass braided wires.
