Abstract
The present disclosure is directed to a thermoplastic composition. The thermoplastic composition comprises: a) a copolyether-ester; b) an ethylene acrylic copolymer as defined; and c) aluminum trihydrate (ATH), present in an amount of at least 40% by weight of the thermoplastic composition; wherein the weight ratio of the copolyether-ester to the ethylene acrylic copolymer in the thermoplastic composition ranges from 98:2 to 65:35. The present disclosure is also directed to a wire or cable jacket formed from the thermoplastic composition.

1-31. (canceled)
A thermoplastic composition comprising:
- a) a copolyether-ester;
- b) an ethylene acrylic copolymer comprising:
- i) copolymerized units of a monomer having the structure:
- wherein R1 is hydrogen C1-C12 alkyl, and R2 is C1-C12 alkyl, C1-C20 alkoxyalkyl, C1-C12 cyanoalkyl, or C1-C12 haloalkyl, and wherein the polymerized units of the monomer are present in an amount ranging from about 40% to about 70% by weight of the ethylene acrylic copolymer;
- ii) copolymerized units of an unsaturated carboxylic acid or an anhydride thereof, present in an amount of at least 2% by weight of the ethylene acrylic copolymer;
- and
- iii) copolymerized units of ethylene;
- and
- c) aluminum trihydrate (ATH), present in an amount of at least 40% by weight of the thermoplastic composition;
- wherein the weight ratio of the copolyether-ester to the ethylene acrylic copolymer in the thermoplastic composition ranges from 98:2 to 65:35.
