Disclosed herein is a process for making elastomeric polyisoprene articles, wherein, the process is a system which produces synthetic polyisoprene articles exhibiting tensile strength property greater than 3000 psi which is similar to that of solvent-based processes using natural rubber latex. The process comprises an accelerator composition at the pre-cure stage comprising a dithiocarbamate, a thiazole and a guanidine compound. In a preferred embodiment, the accelerator composition comprises zinc diethyldithiocarbamate (ZDEC), zinc 2-mercaptobenzothiazole (ZMBT) and diphenyl guanidine (DPG), in conjunction with a stabilizer, such as sodium caseinate, The elastomeric polyisoprene product made by this process is used for making articles, such as a surgeon's glove, a condom, a catheter and a probe cover. |
