  • Publication number: 20080161467
    Abstract: A rubber formulation with good wet traction properties includes one or more elastomers and at least two types of particulate filler materials including at least one of which has a relatively high free surface energy in water (i.e., a supplemental filler). The formulation containing the supplemental filler(s) can provide a vulcanizate that has a British pendulum (skid) number that is at least ˜5% greater than that of a vulcanizate made from an essentially identical formulation that does not contain the supplemental filler(s). Also provided is a method for providing such a formulation which involves identifying one or more supplemental fillers having relatively high free surface energies in water, replacing at least 15% (by wt.) of one or more of the conventional particulate fillers in the formulation with an approximately equivalent volume of supplemental filler particles, and providing the modified formulation.

  • Publication number: 20030114571
    Abstract: The wet traction of a vehicle tire is significantly improved when about 5 phr to about 200 phr of a surface-treated (hydrophobated) siliceous or oxidic filler is included in the vulcanized rubber compound used for the tire tread.

  • Publication number: 20030032712
    Abstract: A polymer gel composition having a Shore A hardness less than 20. The polymer gel composition includes a polymer having at least 2 blocks derived from a vinyl-substituted aromated hydrocarbon, a R1R2ethylene, an alkyl vinyl ether, a maleimide, and a conjugated diene. At least one hydrophobic filler is included and, optionally, an extender. If maleimide is chosen, a maleated polyalkylene and a grafting agent are also included in the polymer composition.
