  • Publication number: 20140216625
    Abstract: A pneumatic tire carcass having a radial direction and a circumferential direction. The tire carcass comprises at least one ply of stabilizing fabric and an air-blocking layer attached to the stabilizing fabric. The stabilizing fabric contains a plurality of reinforcing yarns and is disposed within the carcass such that the reinforcing yarns are arranged in the radial direction of the carcass. The reinforcing yarns comprise monoaxially drawn tape elements having a rectangular cross-section, an upper surface, and a lower surface. The tape elements contain at least a first layer having a draw ratio of at least about 5, a modulus of at least about 2 GPa, and a density of at least 0.85 g/cm3. The first layer contains a polymer selected from the group consisting of polyamide, polyester, co-polymers and mixtures thereof.

  • Publication number: 20130136904
    Abstract: A winder liner for unvulcanized rubber material comprising a first woven layer, a second woven layer, and a polymer layer. The first and second woven layers each contain a plurality of warp tape elements in a warp direction interwoven with a plurality of weft tape elements in a weft direction and a plurality of interstices between the warp and weft tape elements. The polymer layer is disposed on the inner surfaces of the first woven layer and the second woven layer and in the interstices of the first woven layer and the second woven layer. The polymer layer contains a first polymer comprising a co-polymer having at least 50% ?-olefin units and is characterized by a number-average molecular weight of about 7,000 to 500,000 g/mol, and a viscosity of between about 2,500 and 150,000 cP measured at 170° C.
