Patent ID: 8883279

Claim:
A molded product comprising: an injection molded article defining an exterior surface having a surface area and an internal fluid-formed hollow cavity, the article being made from a composition containing a polymer mixture and reinforcing fibers or reinforcing fillers, the polymer mixture comprising from about 45% to about 95% by weight of the composition, the polymer mixture comprising a polyethylene terephthalate homopolymer combined with a polyethylene terephthalate copolymer, the polyethylene terephthalate homopolymer and the polyethylene terephthalate copolymer being present in the polymer mixture in a weight ratio of from about 10:90 to about 70:30, the polymer mixture optionally containing another polyester polymer in an amount from 0% to about 25% by weight, the other polyester comprising a polybutylene terephthalate, a polybutylene naphthalate, a polytrimethylene terephthalate, a polypropylene terephthalate or a polycyclohexylene dimethyl terephthalate, the polymer mixture having a melt flow rate at 265° C. and at a 2160 g load of from about 20 g/10 min to about 50 g/10 min, the exterior surface of the article containing pits in an amount less than about 2.5% of the surface area of the exterior surface.
