Document Type and Number:
WIPO Patent Application WO/2017/209207
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a pneumatic tire inner liner that is highly durable and has high crack resistance at low temperatures. As a solution to said problem, the present invention provides a pneumatic tire inner liner (100) that comprises a film layer (10) and an adhesive layer (20) that is provided on at least one surface of the film layer (10). The pneumatic tire inner liner (100) is characterized in that: the film layer (10) has a gas barrier layer (11) and an elastic layer (12) that is provided on at least one surface of the gas barrier layer (11); the gas barrier layer (11) includes at least a thermoplastic resin; the elastic layer (12) includes at least a polyurethane thermoplastic elastomer; and the adhesive layer (20) includes at least a polystyrene thermoplastic elastomer, the styrene content of the polystyrene thermoplastic elastomer being more than 0 mass% but less than 40 mass%.
