Formulating for Improved Strength of Injection-Molded Unsaturated Polyester Composites

An unsaturated polyester composite TMC^R/BMC formulation has been developed for the injection-molding of large Class A parts. This formulation has demonstrated a consistent ability to meet the automotive industry's requirements for improved Izod impact strength with superior flexural strength and tensile strength plus provide the highest level of surface performance when compared to conventional injection systems.
