Abstract
The present disclosure relates to TPV compositions suitable for foaming, as well as foamed TPV compositions, methods of making the foregoing, and applications of various foamed TPV compositions. The TPV compositions comprise an at least partially vulcanized rubber component dispersed within a thermoplastic component comprising a thermoplastic resin and a propylene-based elastomer, oil, and optionally one or more additives. According to some aspects, the TPV composition may be made in part by preloading some portion of process oil prior to addition of the curative. TPV compositions provided herein are particularly suitable for foaming with thermo-expandable microsphere foaming agents.
