  • Sidewall reinforcing layer for pneumatic tires
    Publication number: 20070251627
    Abstract: A pneumatic tire may include a floating reinforcing layer disposed between a body ply and the sidewall of the tire. The reinforcing layer may extend from a point beneath the rim flange of the wheel to a point just above or below the maximum section width of the tire. By adding stiffness to the sidewall region at and above the rim, the reinforcing layer enhances the durability of the tire without sacrificing ride comfort.

  • Multi-layer nano-particle preparation and applications
    Patent number: 7238751
    Abstract: A multi-layer nano-particle composition including a polymer core and at least two additional layers is provided. The nano-particles have a mean average diameter less than about 100 nm. The nano-particles can be modified via, for example, hydrogenation or functionalization. The nano-particles can be advantageously incorporated into rubbers, elastomers, and thermoplastics.
