Polymer sheet for inner liner and pneumatic tire using the same |
摘要 |
Provided is a pneumatic tire which exhibits excellent performance in flex crack growth resistance, rolling resistance and static air pressure drop, and includes an SIBS layer containing a styrene-isobutylene-styrene triblock copolymer as a polymer sheet used for an inner liner. The SIBS layer has a thickness more than or equal to 0.05 mm and less than or equal to 0.6 mm. The SIBS layer contains more than or equal to 0.5% by mass and less than or equal to 40% by mass of a polymer obtained by polymerization of a monomer unit having 4 carbon atoms. |
