  • Publication number: 20170233549
    Abstract: The present disclosure is directed to rubber compositions containing a chemical additive capable of generating or enhancing strain-induced crystallization into the compositions, and tires containing the rubber compositions in one or more components such as sidewalls or treads. The chemical additive is at least one nucleating agent of formula (I) or formula (II). As well, certain embodiments relate to methods for achieving reduced wear or improved durability in a tire tread or tire sidewall by using the chemical additives.

  • Patent number: 9657157
    Abstract: A rubber composition is provided that includes a partially halogenated diene polymer that has a controllable microstructure, and no more than about 50% of the n repeat units are in blocks of three or more consecutive units. In embodiments, a reinforcing filler is also included in the rubber composition. In embodiment, the rubber composition is formed into a tire component. A method of making the composition is also provided.

  • Patent number: 9562832
    Abstract: A method of measuring wear rate in an actual rubber tire. A section of rubber is cut out of an actual tire below the surface of the tire. The cut out section is attached to the surface of a first wheel. An abrasive substance is attached to the surface of a second wheel. The two wheels are rotated for a predetermined time, in opposite directions, in contact with each other, at uneven rates resulting in some slippage between the surfaces of the two wheels. The wear rate of the rubber tire is measured based on the changes in the cut section over time, in much less time and using less resources than required by conventional wear measurement methods.

  • Patent number: 8975324
    Abstract: A tread rubber composition having improved abrasion resistance is provided. The tread rubber composition comprises a conjugated diene polymer or copolymer, at least one filler, from 2 to 10 phr of liquid polybutadiene, from 2 to 5 phr of zinc oxide and from 1 to 100 phr of process oil. The liquid polybutadiene is functionalized by reaction with unsaturated acid anhydride, has a number average molecular weight of from 3 to 8 kg/mol and an acid number of from 40 to 80. Also provided are methods for preparing the tread rubber composition comprising mixing of the foregoing ingredients by master-batch and final batch steps whereby the abrasion resistance of the tread rubber composition is improved.
