Effect of the vulcanising system on the quality of NR latex condoms

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