REVISITING THE CONVENTIONAL CURE - A NOVEL WAY TO CONTROL HEAT BUILD UP

The phenomenon of reversion which occurs in a NR compound when vulcani zed using a conventional cure (CV) system is well known. Reversion lea ds to the impairment of vulcanizate properties such as modulus, compre ssion set and heat generation. In this paper the effect of a new chemi cal 1,3 bis(citraconimidomethyl)benzene (BCI-MX) will be discussed wit h respect to its mechanism of action and applications, The use of this chemical will allow rubber compounders to take advantage of CV cure s ystems with regard to flex/fatigue properties whilst improving reversi on resistance.
