Investigating the Effect of Vulcanising Coagents and Ageing Stabilisers on the Heat and Corrosion Resistance of Vulcanisates Based on Nitrile Butadiene Rubber

The Effect of Maleinimides on the Properties of a Rubber Compound Based on Nitrile Butadiene Rubber

“…From the viewpoint of the heat stability of mechanical rubber goods, the vulcanisation process for such rubber mixes with the use of peroxides is preferably sulphur vulcanisation, as in this case more stable carbon-carbon bonds are formed by comparison with mono-and polysulphide bonds between the rubber macromolecules. In Sandalov et al, [2] with a low level of dosing of dicumyl peroxide of grade Perkadox BC-FF, satisfactory physicomechanical properties of vulcanisates were obtained, but the compressive set, one of the most important properties for heat-resistant rubber compounds, remained high in this case. To improve the compression set, it was required to increase the amounts of peroxide, which was also necessary to compensate for the inhibiting action of the antioxidant and other substances absorbing free peroxide radicals.…”
