Abstract
A flame retardant composition is provided which is less expensive to produce than prior compositions and yet which exhibits desirable insulation properties, flame and fire resistance, and which, when ignited, does not emit noxious smoke or corrosive gases. The crosslinkable flame retardant composition includes a copolymer of ethylene and a vinyl ester of a C.sub.2-6 aliphatic carboxylic acid, a hydrated inorganic filler, and a coupling agent.
Claims13
A crosslinkable flame retardant composition consisting of :
- (a) a copolymer of ethylene and a vinyl ester of a C.sub.2-4 aliphatic carboxylic acid;
- (b) a hydrated inorganic filler selected from the group consisting of hydrated calcium borate, hydrated aluminum oxides, hydrated magnesia, hydrated calcium silicate, and mixtures and blends thereof;
- and
- (c) a coupling agent comprising oxalic acid, said composition characterized by the absence of silane compounds.
