In the consumer applications, the elastomer performance needed is processability, colorability and softness. Most Dynaflex® (Styrenic block copolymer TPE), Versaflex® (polar modified alloys) and Versalloy® (TPV alloy compounds are suitable for two-shot or insert molding with a polypropylene (PP). The consumers’ preference for a soft touch, "warm" feel and a personalized color palette drives the use of TPEs in personal care products.
