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 composition comprising a migratory siloxane polymer physically dispersed in a first thermoplastic material and (iv) a second polysiloxane composition comprising a non-migratory, siloxane polymer bonded to a second thermoplastic material.

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.

Abstract: Provided is a composition thermoplastic elastomer structure comprising (1) a first component comprising a first elastomeric component comprising an at least partially vulcanized rubber and a thermoplastic resin, (2) an adhesive later comprising a grafted random propylene copolymer and (3) a third component comprising a polyamide or polyester. The third component is at least partially adhered to the adhesive component, which is in turn, partially adhered to the first component. The structure has superior adhesive properties between structures. Also provided are articles made from the structures, particularly automotive weather seals, glass run channels, a noise attenuating device, automotive interior part, automotive belt, automotive hose, industrial belt, industrial hose, packaging material, construction material, decorative building material, and other consumer goods.

Abstract: Elastomeric polymers that have been functionalized are shown to provide superior extruded profiles for use in vehicle sealing systems. Generally the, polymers functionalized are the ethylene, -alpha-olefin, non-conjugated diene monomer terpolymers or ethylene, -alpha-olefin copolymers. The elastomeric polymers are functionalized with one or more of carboxylic acids, anhydrides, hydroxyl, epoxide or amine functionality. The functionalized elastomeric polymers are generally used in conjunction with non-functionalized elastomeric polymers. The functionalized elastomeric polymers provide superior adhesion to the additional components used to enhance functionality and/or aesthetics. Among the vehicle sealing systems discussed are glass run channels, inner belt line seals, outer belt line seals and door seals.

Abstract: Motor vehicle brake parts based on an ethylene, alpha-olefin, vinyl norbornene elastomeric polymer are manufactured with more efficiency due to brake part compounds having lower viscosity, faster and fuller cures than ethylene, alpha-olefins, diene monomer compounds, where the diene monomer is other than vinyl norbornene. Additionally, the brake parts based on the ethylene, alpha-olefin, vinyl norbornene elastomeric polymer have improved resistance to elevated temperature properties, and good heat aging characteristics, compared to for instance ethylene, alpha-olefin, non-conjugated diene elastomers (where the diene is other than vinyl norbornene) or styrene butadiene rubbers.
