  • Shrinkable thermoplastic vulcanizate and method and article
    Patent number: 11186753
    Abstract: 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>110° C. and a propylene-based elastomer (PBE) having a Tm<110° C.; and heating the article to a temperature between about 100° C. and 250° C. to shrink the article.
    Type: Grant
    Filed: August 1, 2017
    Date of Patent: November 30, 2021
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Wanli Wang, Michael W. Bednarik, Peite Bao, Yi Ping Ni, Ying Ying Sun
  • Foamed Thermoplastic Vulcanizate and Methods Related Thereto
    Publication number: 20210221973
    Abstract: Foamed thermoplastic vulcanizate compositions having minimal water absorption, and in particular having predominantly closed cell structure. The foam compositions exhibit desirable properties including, but not limited to, low density, tensile strength, ultimate elongation, and low modulus of elasticity. The foam may be used in one or more commercial products or articles, such as use in forming weather seals.

  • Compositions comprising thermoplastic vulcanizate, foamed material and articles made therefrom
    Patent number: 9822231
    Abstract: 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.
