Strip, method for manufacturing the same, and method for manufacturing pneumatic tire

A strip of a thermoplastic elastomer composition to be wound spirally on a cylindrical drum to form an inner liner for a tire having a shape close to a finished sectional shape,

• the strip being composed of a layer stack of a first layer made of a thermoplastic elastomer composition containing 0.1 part by mass to 50 parts by mass of an organic derivative of clay mineral relative to 100 parts by mass of an elastomer component made of a styrene-isobutylene-styrene triblock copolymer, and a second layer made of a thermoplastic elastomer composition containing at least one of a styrene-isoprene-styrene triblock copolymer and a styrene-isobutylene diblock copolymer,
• said strip having a strip main body and ear portions disposed on opposite sides thereof, said strip main body having a thickness of 0.05 mm to 1.0 mm, and said ear portions having a thickness thinner than the thickness of said strip main body and a width of 0.5 mm to 5.0 mm.

A strip of a thermoplastic elastomer composition to be wound spirally on a cylindrical drum to form an inner liner for a tire having a shape close to a finished sectional shape,

• the strip being composed of a layer stack of a first layer made of a thermoplastic elastomer composition containing 60 percent by mass to 99.9 percent by mass of a styrene-isobutylene-styrene triblock copolymer and 0.5 percent by mass to 40 percent by mass of a styrene-maleic anhydride copolymer, and a second layer made of a thermoplastic elastomer composition containing a styrene-isoprene-styrene triblock copolymer,
• said strip having a strip main body and ear portions disposed on both sides thereof, said strip main body having a thickness of 0.05 mm to 1.0 mm, and said ear portions having a thickness thinner than the thickness of said strip main body and a width of 0.5 mm to 5.0 mm.

A strip of a polymer composition to be wound spirally on a cylindrical drum to form an inner liner for a tire having a shape close to a finished sectional shape,

• said strip being composed of a layer stack of a first layer of a polymer sheet of a polymer composition containing more than or equal to 0.1 part by mass and less than or equal to 5 parts by mass of sulfur relative to 100 parts by mass of a polymer component containing more than or equal to 5 percent by mass and less than or equal to 40 percent by mass of a styrene-isobutylene-styrene triblock copolymer and more than or equal to 60 percent by mass and less than or equal to 95 percent by mass of at least one kind of rubber component selected from the group consisting of a natural rubber, an isoprene rubber and a butyl rubber, and a second layer made of a thermoplastic elastomer composition,
• said strip having a strip main body and ear portions disposed on both sides thereof, said strip main body having a thickness of 0.05 mm to 1.0 mm, and said ear portions having a thickness thinner than the thickness of said strip main body and a width of 0.5 mm to 5.0 mm.
