Vulcanisation Activators

Vulcanisation activators are products which have a strong activation effect on the cross linking reactions of diene rubbers. The vulcanisation speed is enhanced, and the cross-link density and reversion resistance are increased, particularly when used in high doses. In most cases the dynamic properties of the vulcanised products are clearly improved. Furthermore, additives like Struktol Aktivator 73 A or Struktol ZEH can either supplement or completely replace the use of stearic acid, without running the risk of increased bloom.
