▎ 摘　　要

NOVELTY - Rubber composition comprises: styrene butadiene; silicon dioxide; organosilane; and graphene, where the graphene has a thickness of less than 3.2 nm, a particle size of 50 nm to 10 μ m, and contains greater than 95% carbon. USE - The rubber composition is used as silica tread composition, seals, gaskets, medical gloves, beverage bottles, and chemical and solvent resistant gloves, preferably a silica tread composition (claimed) for automobile tires, light truck tires, and tires for commercial vehicles. ADVANTAGE - The composition provides product with increased barrier protection for tire inner liners, with no tradeoffs in other characteristics.
