It was observed that tensile properties, burst volume and burst pressure of NR latex condoms vary significantly with vulcanising system. When one component of the control accelerator system was replaced, ageing resistance was found to be improved. Higher concentrations of ZMBT adversely affected tensile strength, burst volume and burst pressure after ageing at 70 degrees C, It was also observed-that as the concentration of sulphur increased, mechanical strength of condoms increased as shown by increased tensile properties, burst volume and burst pressure; however this was accompanied by a decrease in ageing resistance.
