Abstract: Provided herein are cured rubber compositions containing guayule natural rubber with 2.5-4 weight % resin and fillers. By the use of a specified cure package that contains increased amounts of sulfur and accelerator, the cured rubber compositions are found to exhibit strain induced crystallization (as can be observed by X-ray diffraction). Also provided are related methods for preparing the rubber compositions.

Abstract: Methods are described for treatment of aramid fibers to modify the surface of the fibers. The treated fibers have improved adhesion to elastomer materials as compared to untreated fibers. Modification methods include irradiating the fibers, compressing and straining the fibers under a constant pull force and immersing the fibers in a coupling agent fluid. The treated fibers can be used with elastomers and provide reinforcement elements in products such as tires.

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.
