Development of Thermoplastic Polyurethane/ABS Blends for Flexible Automotive Bumper Fascia

Thermoplastic polyurethane/ABS blends are being developed by The Dow Chemical Company to meet the high performance requirements for flexible bumper fascia. Features of these blends include paintability without priming, excellent low temperature impact after painting, good heat resistance, and lower specific gravity than other high performance thermoplastic materials. Thermoplastic polyurethane/ABS blends also have excellent flow properties, which will allow large, complex parts with thin walls to be molded easily.
