摘要：
A material for making elastomeric nitrile rubber articles is disclosed. Inparticular, the process and material formulation can produce nitrile rubberbased articles, which exhibit force-strain characteristics that are comparableto those of natural rubber latex articles, while maintaining the tensilestrength properties of nitrile rubber. The process includes an acceleratorcomposition at the pre-cure stage having a dithiocarbamate, a thiazole, and aguanidine compound. The invention also includes an elastomeric nitrile rubberproduct made by the process, such as examination, surgical, or work gloves,which can have an exterior coating over naked rubber selected from either asilicone emulsion or oil, glycerin solution, a combined mixture of siliconeand glycehn/glycerol, a fluorocarbon release agent, or a natural or synthetichydrocarbon-based oil in amounts that do not degrade said substrate rubbermaterial.
