Halobutyl/epoxidized rubber matrices reinforced with siliceous filler materials

摘要

Vulcanizable elastomeric compositions comprise a halobutyl rubber matrix, an adhesion-promoting amount of a epoxidized natural rubber and a reinforcing amount of a siliceous inorganic filler material; the vulcanizates produced therefrom are well suited, for example, as impermeable sealing layers/coatings for tire carcasses.
