A cured elastomer comprising: an elastomer at 100 parts per hundred rubber (phr); and an expandable thermoplastic microsphere at about 0.1 to about 10 phr. Such a cured elastomer can be used, optionally with additives, in an air barrier article that is selected from the group consisting of a tire innerliner, a pneumatic tire, a tire curing bladder, an air sleeves, a diaphragm, and a hose. With microspheres the compounded cured elastomer shows a reduction in specific gravity and a reduction in permeability. Both of these properties are highly desirable in tire design and performance.
