A process of heat shrinking an article is provided. The process includes shaping a thermoplastic vulcanizate (TPV) into an article, the TPV having: a partially vulcanized rubber dispersed in a continuous thermoplastic phase, wherein more than 5 wt % of the rubber is extractable in boiling xylene, and wherein the thermoplastic phase comprises a thermoplastic resin having a Tm&#x3e;110&#xb0; C. and a propylene-based elastomer (PBE) having a Tm&#x3c;110&#xb0; C.; and heating the article to a temperature between about 100&#xb0; C. and 250&#xb0; C. to shrink the article.

Shrinkable thermoplastic vulcanizate and method and article

The present disclosure relates to a composition comprising a thermoplastic vulcanizate, a propylene-based elastomer and a foaming agent, and to a foamed material comprising said composition. The foamed material has increased tensile properties and tension set while attaining comparable effects of reduction of weight.
