Disclosed is a low-permeable rubber laminate which is obtained by arranging a low-permeable resin composition layer (A) on one side of a rubber composition layer (B). The low-permeable resin composition layer (A) has an air permeability coefficient at 30˚C (as measured in accordance with JIS K7126) of not more than 0.5 × 10-12 cc·cm/cm2·sec·cmHg, an average thickness d of 0.05 μm < d < 5 μm, and a Young's modulus E at 160-200˚C of 0.5 MPa < E < 300 MPa. The low-permeable rubber laminate is excellent in air pressure maintaining performance and durability, and enables to prevent occurrence of blisters during formation of a pneumatic tire. Also disclosed is a pneumatic tire using such a low-permeable rubber laminate in an inner liner. |
