    Abstract: A material for making elastomeric nitrile rubber articles is disclosed. In particular, the process and material formulation can produce nitrile rubber based articles, which exhibit force-strain characteristics that are comparable to those of natural rubber latex articles, while maintaining the tensile strength properties of nitrile rubber. The process includes an accelerator composition at the pre-cure stage having a dithiocarbamate, a thiazole, and a guanidine compound. The invention also includes an elastomeric nitrile rubber product made by the process, such as examination, surgical, or work gloves, which can have an exterior coating over naked rubber selected from either a silicone emulsion or oil, glycerin solution, a combined mixture of silicone and glycerin/glycerol, a fluorocarbon release agent, or a natural or synthetic hydrocarbon-based oil in amounts that do not degrade said substrate rubber material.
