To provide a multilayer structure that may adhere to rubber material without the necessity of providing an adhesive layer, an inner liner and a pneumatic tire using the multilayer structure. According to the present invention, a multilayer structure 1 is formed by alternately laminating elastomer layers 3 containing thermoplastic elastomer and barrier layers 2 containing a gas barrier resin, wherein an outermost layer 4 laminated uppermost among layers constituting the multilayer structure 1 contains an elastomer component that may heat-adhere to diene rubber.

摘要:
The present invention relates to a rubber composition capable of sustaining improved on-ice performance of a tire over a long period of time. Specifically, the present invention provides a rubber composition having a rubber component (A) and a composite fiber (B), wherein the composite fiber (B) comprises: a fiber (B1) made of a hydrophilic resin; a covering layer (B2) made of a resin having an affinity for a rubber component and provided to cover at least a portion of the fiber; and a bonding layer (B3) present at least in a portion of an interface between the fiber (B1) and the covering layer (B2) and having affinities for both the hydrophilic resin and the resin having an affinity for the rubber component.
摘要:
The present invention provides a rubber sheet having a thickness of 500 μm or less, wherein a rubber component in a rubber composition to constitute the rubber sheet contains a liquid elastomer having a weight-average molecular weight of from 500 to 100000, and a method for producing a rubber sheet having a thickness of 500 μm or less, which includes a step (A) of forming a film of a rubber composition not containing an organic compound having a boiling point not higher than 150° C., on a substrate sheet at a temperature at which the viscosity of the rubber composition falls within a range of from 10 to 100000 mPa·s. Using the specific liquid elastomer, the present invention provides a rubber sheet having a thickness of 500 μm or less. Not using any special coating apparatus, the present invention provides a method for producing a rubber sheet of a rubber composition not containing an organic compound having a boiling point not higher than 150° C.
