Product Details
Ceramifiable Silicone Rubber Tape
A composite tape that turns ceramic when exposed to fire, forming a hard insulating shell that holds the circuit together. The surface is flat, smooth and free of voids, glue bleed or mechanical impurities.
It is used in MV/LV fire-resistant cables, flexible fire-resistant cables, fire-resistant power and control cables, mining and marine cables, and fire-resistant instrument, signal, data, coaxial and optical cables.
