Glass fiber reinforced polyethylene terephthalate molding resin compounds with low warpage and increased spiral flow which crystallize rapidly after being injection molded and which have engineering resin performance characteristics are provided. In addition to polyethylene terephthalate and glass fibers, the compounds contain glass flakes, an aliphatic polyester, an ionic hydrocarbon polymer, an antioxidant, and, optionally, polyethylene and/or a polymeric epoxy compound. Sodium stearate and/or polyester amide resins may also be added to improve surface finish. The compounds can be flame retarded with a brominated polystyrene and an antimonate without substantial loss of, or change in, properties. |
