Vulcuren® is a new crosslinker for the production of highly reversion stable vulcanizates of NR, IR, SBR and BR and their blends. Diene rubber compounds crosslinked with Vulcuren® do not show the usual fall in mechanical properties on overcure or high temperature cure that is seen in traditional vulcanization systems. Also vulcanizates crosslinked with Vulcuren® and subjected to dynamic stress after overcuring or curing at high temperatures retain their original properties better than vulcanizates made with current crosslinking systems. Vulcuren® is recommended in combination with sulfur and accelerators such as mercaptobenzothiazoles or sulfenamides in conventional and semiefficient vulcanization systems.Information provided by Lanxess. |
