Abstract
A method of preparing a green tire innerliner, the method comprising mixing one or more vulcanizable rubbery polymers, less than 0.75 parts by weight zinc oxide, less than 0.75 parts by weight magnesium oxide, and less than 0.75 parts by weight sulfur, per 100 parts by weight rubber, to form a vulcanizable mixture and extruding the mixture to form a green tire innerliner.
Claims18
A tire comprising an innerliner, where the innerliner includes a rubber composition that is at least partially cured, and where the rubber composition is characterized by a swollen polymer volume fraction (Vr) of less than 0.15.
A tire comprising an innerliner, where the innerliner that is prepared by at least partially curing a rubber composition that comprises one or more vulcanizable rubbery polymers, less than 0.75 parts by weight zinc oxide, less than 0.75 parts by weight magnesium oxide, and less than 0.75 parts by weight sulfur, per 100 parts by weight rubber.
