RUBBER COMPOSITION FOR INNER LINER AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic tire improving maneuvering stability compatible with comfortableness to ride in a well balanced state while maintaining air holding properties and durability. SOLUTION: A rubber composition for an inner liner comprises <1 pt.wt. of sulfur in 100 pts.wt. of a polymer component composed of≥40 pts.wt. of butyl rubber and/or a halogenated butyl rubber, 3-30 pts.wt. of a block copolymer composed of a styrenic polymer block and an isobutylene-based polymer block and a diene-based rubber. The pneumatic tire is obtained by using the composition in the inner liner. COPYRIGHT: (C)2008,JPO&INPIT
