  • Patent number: 11970618
    Abstract: A vulcanizable rubber composition comprises an interpenetrating or ionic network (IPN)-promoting resin. The resin comprises side chain functional groups along the resin backbone, which, in the presence of an additive material, form the connections that make up the IPN. In one embodiment, such material is ZnO. A method for forming the rubber composition comprises, in a productive step, mixing the product of the non-productive step, the zinc oxide, and a resin derived from maleic anhydride. The zinc oxide and the resin are simultaneously added to the composition during the productive mixing stage. The rubber composition can be cured and incorporated in a tire component, such as, a tread.

  • Publication number: 20240132697
    Abstract: A sulfur-vulcanizable rubber compound comprises a silane functionalized diene elastomer, a dual silane coupling system, and a silica filler. The non-active sulfur containing silane coupling agent excludes an active sulfur moiety. The rubber compound is a reaction product of a siloxyl condensation reaction between the silane functionalized diene elastomer and the dual silane coupling system. The dual coupling system comprises a non-active sulfur containing silane coupling agent for reacting with an associated precipitated silica to produce a hydrophobic silica; and a crosslinking reagent for reacting with the non-active sulfur containing silane coupling agent and an associated polymer.

  • Publication number: 20230173847
    Abstract: A pneumatic tire having a fiber-reinforced rubber layer can help prevent foreign objects from penetrating/extending beyond the tread and into its underlying layer(s), thereby desirably increasing the overall lifespan of the tire. In one embodiment, the tire includes at least one fiber-reinforced rubber layer, which can be generally supported by a tire carcass and interposed directly between a tread portion and belt ply. The fiber-reinforced rubber layer can define a barrier/barrier layer between the tread portion and belt ply and includes a rubber compound that is reinforced with one or more types of fiber (e.g., chopped nylon fiber) and has one or more specific chemical compounds that can provide desirable barrier properties (e.g., abrasion resistance, penetration energy, and DIN properties), thereby helping to prevent foreign objects from penetrating/extending beyond the tire tread and into its underlying layer(s), such as the belt ply and carcass.
