Claims23
A light-emitting diode housing comprising a poly(1,4-cyclohexanedimethanol terephthalate) composition comprising:
- (a) about 40 to about 95 weight percent poly(1,4-cyclohexanedimethanol terephthalate);
- and
- (b) about 15 to about 50 weight percent of rutile titanium dioxide;
- (c) 0 to about 40 weight percent of one or more inorganic reinforcing agent and/or one or more inorganic filler;
- (d) 0 to about 3 weight percent of one or more oxidative stabilizer;
- and
- (e) a polymeric toughener comprising an ethylene/(meth)acrylate copolymer and/or an ethylene, ethyl acrylate or n-butyl acrylate, and glycidyl methacrylate terpolymer;
- wherein the weight percentages are based on the total weight of the composition;
- and
- wherein the light-emitting diode housing has a cavity that surrounds a light-emitting diode.
