Patent ID: 8604105

Claim:
A copolyester composition comprising: (a) from about 96 to less than 98 weight % of the copolyester, the copolyester comprising (i) a diacid component comprising from 70 to 100 mole % residues of terephthalic acid, from 0 to 30 mole % residues of a modifying aromatic diacid having from 8 to 12 carbon atoms, and from 0 to 10 mole % residues of an aliphatic dicarboxylic acid; and (ii) a glycol component comprising from 1 to 65 mole % cyclohexanedimethanol residues and from 35 to 99 mole % of a modifying glycol having 2 to 20 carbon atoms; (b) from greater than 2 to about 4 weight % of a flame retardant mixture comprising (i) a melamine and (ii) a metal phosphinate, wherein the copolyester composition has (1) a UL 94 V0 rating or (2) a Class 1 or Class A rating according to ASTM E-84, wherein the copolyester composition has an energy at maximum load greater than 8 Joules measured on a 100 mm×100 mm×1.5 mm plaque according to ASTM D3763, wherein the weight % is based on the weight of the copolyester, wherein the total mole % of the dicarboxylic acid component is 100 mole % and the total mole % of the glycol component is 100 mole %.
