Abstract
The present disclosure provides a low-smoke, non-halogenated flame retardant composition made from or containing (a) a first ethylene/vinyl acetate copolymer, having a total content of vinyl acetate-derived units in an amount from about 15 to about 45 weight percent, based upon the total weight of the ethylene/vinyl acetate copolymer; (b) a coupling agent; (c) magnesium dihydroxide; (d) hydromagnesite; and (e) huntite.

A low-smoke, non-halogenated flame retardant composition comprising:
- (A) about 15 to about 25 weight percent, based upon the total weight of the low-smoke, non-halogenated flame retardant composition, of an ethylene/vinyl acetate copolymer having a total content of vinyl acetate-derived units in an amount from about 25 to about 30 weight percent, based upon the total weight of the ethylene/vinyl acetate copolymer;
- (B) about 8 to about 12 weight percent of the coupling agent, based upon the total weight of the low-smoke, non-halogenated flame retardant composition;
- (C) about 20 to about 40 weight percent of magnesium dihydroxide, based upon the total weight of the low-smoke, non-halogenated flame retardant composition;
- (D) about 10 to about 20 weight percent of hydromagnesite, based upon the total weight of the low-smoke, non-halogenated flame retardant composition;
- and
- (E) about 10 to about 20 weight percent of huntite, based upon the total weight of the low-smoke, non-halogenated flame retardant composition.
