RUBBER COMPOSITION FOR INNER LINER

摘要

A rubber composition for the inner liners of pneumatic tires which comprises a rubber ingredient and a lamellar or flaky mineral having an aspect ratio of 3 to 30, excluding 30; a process for producing the rubber composition; and a pneumatic tire made with the rubber composition. The composition is applicable to tires for automobiles, buses, motor trucks, and aircraft. The composition has significantly improved impermeability to air and improved processability. During tire production, an unvulcanized sheet thereof is less apt to break or come to have holes. The pneumatic tire produced with the rubber composition as an inner liner rubber can have a reduced weight because the inner liner can have a reduced gauge while maintaining an internal pressure of the tire.
