Abstract: A flame resistant insulated electrical wire and/or cable construction formed by wrapping a wire or cable conductor with a heat resistant flexible refractory tape comprising a porous base fabric, preferably a knit fiberglass fabric that has been coated and impregnated with refractory materials. These refractory materials are bonded to both the surface and interstices of the base fabric by means of a bonding agent, such that the fabric remains flexible and retains its stretch properties. In the presence of relatively extreme temperature and heat (e.g., above 1750.degree. F.), the bonding agent will decompose without flaming, while the refractory materials will fuse into the softened surface of the knit fiberglass base fabric forming a high temperature resistant structure with ceramic qualities and insulative properties.

Abstract: A laminated fiberglass fabric composition is prepared by laminating a non-woven fabric to a knitted or woven fiberglass fabric with a plastisol laminating adhesive. Heat compressing the assembled materials envelops the individual fiberglass yarns with the non-woven fabric producing a fabric composition which is highly resistant to damage caused by severe twisting or flexing forces applied to the fabric. The use of a flame resistant laminating adhesive imparts flame resistant to these fabric compositions.
