Refrasil® – Vitreous Silica Fiber

Vitreous Silica fibre is designed for extreme temperature applications. Vitreous Silica fibre in this design is braided with insulation on the individual conductors and the jacket giving a continuous temperature rating up to 982 °C (1800 °F). The vitreous silica fibre 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.
