  • Patent number: 8501859
    Abstract: A carbon black reinforced rubber composition which contains hydrophilic sorbitan monostearate and specialized tackifying resin and a pneumatic rubber tire having a visually observable rubber component, such as for example a rubber sidewall, of said rubber composition. The surface of said rubber composition, namely the tire sidewall rubber component, in its uncured state contains said hydrophilic sorbitan monostearate on its surface together with said specialized tackifying resin to promote enhanced building tack and thereby counteract building tack loss by the sorbitan monostearate having been exposed to moisture (moisture exposed surface) during the processing of the rubber composition, particularly after its high shear processing such as, for example, extrusion.

  • Publication number: 20130190442
    Abstract: The linear low density polyethylene nanocomposite fibers are formed from a linear low density polyethylene matrix having carbon nanotubes embedded therein. The addition of the carbon nanotubes enhances the overall toughness of the material, resulting in increases over conventional linear low density polyethylene in the material's tensile strength, elasticity and ductility. The carbon nanotubes constitute between about 0.08% and 1.0% by weight of the linear low density polyethylene nanocomposite fiber. Optimal toughness is found at about 0.3 wt %. The linear low density polyethylene nanocomposite fibers are made by first melting a quantity of linear low density polyethylene, and then blending a quantity of carbon nanotubes into the melted linear low density polyethylene to form a mixture, The mixture is then extruded to form the linear low density polyethylene nanocomposite fibers, which are then spun in a spinneret die to produce the finished linear low density polyethylene nanocomposite fibers.

  • Patent number: 8394190
    Abstract: The invention relates to carbon black granulates having an APC value, measured at a conveying speed of 8 m/s and a solid load of 27 g/kg, less than or equal to 20 and a 25 [mu]m pressure filter value of less than 5 bar cm2/g. The carbon black granulate is produced by carbon black powder being pre-granulated in a first mixing granulator with addition of a granulation liquid with or without binders and being granulated to a finished state in a second mixing granulator without further addition of granulation liquid. The carbon black granulate can be used as a filler, reinforcing filler, UV stabilizer, conductive carbon black, pigment, or reducing agent.

  • Patent number: 8378017
    Abstract: The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions.
