  • Patent number: 11447624
    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, including in glass run channels. The TPV compositions comprise an at least partially vulcanized rubber component dispersed within a thermoplastic component comprising a first thermoplastic resin. According to some aspects, the TPV composition may be combined with a high melt-strength thermoplastic resin, and in particular a high melt-strength polypropylene-based thermoplastic resin, to make a foamable TPV composition. The foamable TPV composition (with or without high melt-strength thermoplastic resin) is then coextruded or otherwise combined with foaming agent (preferably comprising thermo-expandable microspheres) to form the foamed composition.

  • Patent number: 11359083
    Abstract: A thermoplastic vulcanizate composition comprises: (i) a dispersed phase of rubber that is at least partially cured; (ii) a continuous thermoplastic phase including at least one thermoplastic polymer; (iii) a first polysiloxane comprising a migratory liquid siloxane polymer; and (iv) a second polysiloxane comprising a non-migratory siloxane polymer bonded to a thermoplastic material.

  • Patent number: 11192992
    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.

  • Publication number: 20180319961
    Abstract: The present disclosure relates to reaction products formed from a thermoplastic vulcanizate compositions, articles made therefrom, and methods for making such reaction products. The reaction products may include a thermoplastic vulcanizate, a functionalized polymer, and an inorganic filler. Such reaction products may advantageously exhibit reduced coefficient of linear thermal expansion as compared to a product that is otherwise identical, but which do not contain the functionalized polymer and/or inorganic filler. The reaction product may be used in automotive extruded sealing profiles, such as glass run channel, glass encapsulation, and belt line seals.
