Abstract: The present invention is directed to a composite material comprising a vulcanizable polychloroprene rubber composition and textile fibers, the fibers having distributed over surface portions thereof an adhesive comprising a resorcinol-formaldehyde resin and a copolymer of from about 1 weight percent to about 10 weight percent 2,3-dichloro-1,3-butadiene and from about 90 weight percent to about 99 weight percent chloroprene.

Abstract: One aspect of the invention is directed to a rubber cure system that includes: an amine-free accelerator; a bismaleimide; and an alkylphenol disulfide. Another aspect of the invention is directed to a rubber composition including: at least one sulfur-vulcanizable elastomer containing olefinic unsaturation; an amine-free accelerator; a bismaleimide; and an alkylphenol disulfide. In a further aspect, the invention includes a rubber composition in the form of a product. If desired, the product may include a reinforcing cord comprising a polyester. Examples of products of the invention include a tire ply, a tire belt, a tire overlay, a pneumatic tire, an airspring, a conveyor belt, a hose, and a power transmission belt.

Abstract: Disclosed is a tire having at least one reinforcing ply in the carcass, belt, or bead region of the tire. The reinforcing ply is comprised of a blended fiber cord. The cords, in combination with a preferred cure temperature adhesive, achieve a high degree of thermal stability allowing for the use of such cords in various reinforcing plies for a pneumatic tire and for preferred use for such cords in areas of the tire subject to high temperatures either in curing or performance.
