CBSI and TBSI do not fundamentally differ from each other in their effect on vulcanisation; the vulcanisation speed of the sulphenimides is lower than that of sulphenamides derived from primary amines, and also lower than the vulcanisation speed with MBS, but greater than that with DCBS; the sulphenimides do not have a bad effect on thermo-oxidative ageing of the vulcanisates; they have positive effect on the resistance of rubber to overcuring; sulphenimides have a good effect on rubber-steel cord adhesion particularly during overcuring; sulphenimides are very stable materials, and their effectiveness remains unchanged even under extreme storage conditions; sulphenimides have a good effect on the dynamic properties of rubber, particularly in the case of overcuring; the use of sulphenimides can provide a reliably alternative in the future to MBS and possibly DCBS.
