    摘要: Films of thermoplastic polyurethanes (TPU) with a Shore hardness of 75 A to 92 A having 5 to 20% by weight of polyether amide block copolymers and/or polyether ester block copolymers, and their use for adhering to other substrates, particularly for back-foaming with polyurethane foam. The invention also relates to the use of an addition of 5 to 20% by weight of polyether amide block copolymers and/or polyether ester block copolymers to thermoplastic polyurethanes with Shore hardnesses of 75 A to 92 A, based on the weight of the thermoplastic polyurethanes, for decreasing the adhesion and/or interlocking of thermoplastic polyurethanes produced by single layer blown extrusion technique.

    摘要: The present invention relates to a process for forming composite shaped articles used for athletic shoe soles, tubes, pipes, transmission belts and conveyor belts, comprising a vulcanized elastomer directly or autogenously bonded, that is, essentially in the absence of adhesive, to a thermoplastic elastomer comprising recurring polyamide-6 and polyether structural units, such as thermoplastic polyetheresteramide elastomers, are provided. The article is prepared by a process comprising placing a thermoplastic elastomer component into a vulcanization mold, overmolding onto at least a portion of the surface area of one face surface of the thermoplastic elastomer component with a vulcanizable elastomer component, and vulcanizing the vulcanizable elastomer component at a temperature below the melting point of the thermoplastic elastomer component but over a wide temperature range, which can be about 40° C. or higher.
