Abstract
A curable elastomer composition comprising an elastomer, an unsaturated carboxylic metal salt such as zinc diacrylate, an organic peroxide curing agent such as a ditertiary alkyl peroxide, and phenothiazine as a precure inhibitor. Suitable elastomers include nitrile rubber, EPDM, and EVA. The nitrile rubber is desirably hydrogenated. A method for curing the curable elastomer composition and the resulting cured elastomer compositions are encompassed.
