Abstract: 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.

Abstract: Thermoplastic vulcanizates (TPVs) may comprise a vulcanizable elastomer rubber, a thermoplastic polymer, and a plasticizer, wherein the plasticizer comprises a solid resin. Methods include introducing to a blender a masterbatch comprising a first thermoplastic polymer and a curative, a vulcanizable elastomer rubber, a second thermoplastic polymer, and 25 parts to 250 parts of a plasticizer by weight of the vulcanizable elastomer rubber. The first and second thermoplastic polymers combined are 20 parts to 250 parts by weight of the vulcanizable elastomer rubber, and the plasticizer comprises a solid resin. The masterbatch, thermoplastic resin, and plasticizer are then dynamically vulcanized in at least a portion of the vulcanizable elastomer rubber to form a thermoplastic vulcanizate.

Abstract: To obtain an elastomeric composite crumb having a majority of the particle size distribution greater than 0.33 cm, the crumb is obtained by a process whereby the elastomeric composite comprises less than about 0.5 phr of a salt of a C8 to C20 carboxylic acid, or 10 to 20 phr of a tackifying resin or a combination of both an absence of carboxylic acid and the presence of the tackifying resin. The use of one or both methods permits control of crumb particle size distribution in emulsion or solution processes for producing elastomeric nanocomposites. The elastomeric composite is also disclosed.
