A. Schulman to showcase new TPEs for automotive applications

A. Schulman, an international supplier of high performance plastic compounds and resins, announced yesterday (Oct 1) the European launch of two new thermoplastic elastomer (TPE) products for automotive applications -- Invision VX EP ultra high-flow TPE, and Invision SLX slush TPE.

Invision VX EP ultra high-flow TPE was developed for multi-component injection molding of large interior parts. It allows manufacturers to mold a base substrate, and then mold another material on top of or adjacent to the base substrate, in a single process step. Previously, this two-shot processing had been prevalent for smaller consumer products, but had not been widely used for soft-touch trim for large automotive parts such as instrument panels, door panels, door bolsters and armrests.

The new ultra high-flow TPE from Invision also allows automakers to achieve greater design flexibility, such as multi-touch and multi-tone designs, as well as improved craftsmanship, including outstanding grain definition, high-contrast colors, clean lines, and precise fit and finish. Other advantages of Invision ultra high-flow TPE include low surface gloss, low fogging, good weatherability, and scratch and mar resistance.

Next-generation products are already in development. Similarly, Invision SLX slush TPE offers manufacturers greater flexibility, allowing for designs with desirable sharp radii and deep curves, along with well-defined grains and cast-in color. For instrument panels, door panels and consoles, Invision SLX offers a cost-effective alternative to slush-molded thermoplastic polyurethane (TPU) or sprayed urethane.

According to Jane Maselli, Invision SLX Program Manager, Invision slush TPE has a lower specific gravity and wider processing window than other products, so manufacturers are able to use less material per part and produce thinner skins, while maintaining performance requirements for the finished part. In addition, parts made with Invision slush TPE pass stringent automotive industry requirements relating to odor and emissions, and provide excellent long-term UV stability.

A. Schulman will display the Invision products for the first time in Europe at the FAKUMA show, which will be held from October 14 to 18 in Friedrichshafen, Germany.
