Abstract
Disclosed are elastomer compositions. The elastomer compositions include at least 20% by weight, based on the total weight of the elastomer composition, of a polymer matrix; and (b) 0.1 to 70% by weight, based on the total weight of the elastomer composition, of a solid isocyanate residue of isocyanate manufacturing, the solid having, prior to its inclusion in the elastomer composition, a D90,3 particle size of no more than 70 microns. Elastomer products made using these elastomer compositions can include, for example, a tire treadstock, a tire sidewall stock, a roofing membrane, a door seal, a window seal, a trunk seal, a hood seal, a hose, such as a hose in a vehicular cooling system circuit, or a hanger element attaching an exhaust system to a vehicle underfloor.
