Document Type and Number:
Japanese Patent JP7406068
Kind Code:
B2
Abstract:
Provided is an inner liner which adheres to the carcass or other rubber composition layer of a tire, even during low-temperature vulcanization on the order of 160° C., without using an adhesive or an adhesive tie gum. The invention provides a pneumatic tire inner liner comprising a thermoplastic elastomer composition, characterized in that the thermoplastic elastomer composition includes a thermoplastic resin (a11) having a melting point of 180° C. or lower, or a thermoplastic elastomer (a12) having a melting point of 180° C. or lower and including no residue containing an unsaturated bond derived from a conjugated diene compound, and an elastomer (a2) including a residue containing an unsaturated bond derived from a conjugated diene compound, and the tensile elongation at break of the thermoplastic elastomer composition at 25° C. temperature and 500 mm/min pull speed is 100% or greater.
