Vulcuren® is a new crosslinker for the production of highly reversion-stable vulcanisates 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 vulcanisation systems. Also vulcanisates crosslinked with Vulcuren® and subjected to dynamic stress after overcuring or curing at high temperatures retain their original properties better than vulcanisates made with current crosslinking systems.

Vulcuren® is recommended in combination with sulfur and accelerators such as mercaptobenzothiazoles or sulfenamides in conventional and semi-efficient vulcanisation systems.
