A New Material for Automotive Powertrain Applications: Olefin Based Engineering Polymer Alloys

Thermoplastic engineering materials are expanding in their uses for powertrain applications, ranging from decorative engine covers to intake manifolds and fuel rails. The search for more cost effective materials and reduced weight for these components continues. Hivalloy engineering resin alloys provide the necessary properties and performance required for powertrain applications and offer a variety of benefits versus traditional engineering thermoplastic materials such as nylon, acetal, and polyester products. In addition to significantly reduced weight and cost, other benefits include processability, as molded dimensional stability superior to traditional semi-crystalline resins, and reduced color shift due to heat aging. This paper will cover the product chemistry, product benefits, processing, properties including chemical resistance to powertrain fluids, electrical properties, heat aging, dimensional capability, and mechanical property data with comparisons to other engineering resins.
