ABS-rich PC blend brings weight, cost savings

The latest model Audi Q3 employs a low-cost blend of PC and ABS in which the ratio of ABS is higher than in standard grades for an interior tray component. Two specific colors were designed to meet Audi requirements, truffle beige and soul.

The new material, Pulse GX50 from Styron Automotive (Horgen, Switzerland), has been designed for use in a variety of interior components including mid consoles, lower instrument panels, glove boxes, vents and trunk trims. In its development, Styron worked closely with Audi to fulfill the OEM’s requirements by addressing their specifications and meeting their target cost.

In comparison to Styron’s Pulse A35-105, an engineering resin that has exceptional impact strength even at low temperatures, Pulse GX50 is a more economical alternative due to its lower ratio of polycarbonate to ABS. As a result, a finished part made of Pulse GX50 is approximately 3% lighter and 7% cheaper than the same part molded from Pulse A35-105. Offering this cost-effective solution allows OEMs like Audi to meet the industry’s demand for lightweight, robust and durable materials without compromising quality, performance and cost.

Automakers know that high temperature resistance is an essential feature for automotive parts, and Audi is no exception to the rule. Pulse GX50 fulfills this condition and goes a step further by offering high impact strength at low temperatures while maintaining a tailor made heat distortion resistance. Pulse GX50 reportedly meets processors’ down gauging needs by allowing easy flow for a smooth and highly productive injection molding process. The product’s odor and carbon emission are also reported to be very low, which is an important attribute for interior components.

“An important aspect for automotive suppliers is the effective use of materials. They are always looking for ways to use lighter and cheaper plastics while meeting high safety and environmental standards. Pulse GX50 complies precisely with such needs and that is one of the main reasons it was a success from the start,” explains Marjolein Groeneweg, marketing manager, Styron
