Abstract
The disclosure of this application is directed to compositions having improved flame retardant properties containing an alkylene-alkyl acrylate copolymer, a halogenated flame retardant additive and an oxide, carbonate, hydroxide or sulfate of magnesium or calcium in an amount more than 20 and up to about 30 percent by weight. The compositions disclosed are useful as jacketing material and as insulation about wire and cable.
Claims22
A flame retardant alkylene-alkyl acrylate copolymer composition comprising an alkylene-alkyl acrylate copolymer, from about 1 to 30 weight percent of a halogenated flame retardant additive, and more than 20, up to about 30 weight percent of at least one of calcium or magnesium oxide, carbonate, hydroxide or sulfate;
- said weight percents based on the total weight of the composition.
A flame retardant composition comprising an ethylene-ethyl acrylate copolymer, from about 1 to 30 percent by weight of the halogenated flame retardant additive, ethylene bis(tetrabromophthalimide) and more than 20, up to about 30 weight percent of at least one of calcium or magnesium oxide, carbonate, hydroxide or sulfate, said weight percents based on the total weight of the composition.
