Accelerator CBTS

Accelerator CBTS by Akrochem is a delayed action sulfenamide accelerator for natural- and synthetic rubbers. It offers better scorch resistance than thiazoles and more scorch safety than BBTS. It is available as a polymeric masterbatch and can be used in combination with secondary accelerators. In Accelerator CBTS, polymer-bound or encapsulated dispersion is used to upgrade plant safety, quality and raw material control. It can be accelerated by thiurams and dithiocarbamates to give shorter cure times. Recommended dosage range is 0.5-3.0 phr, with a higher level typically being used in concert with an efficient-vulcanization system and reduced sulfur levels.
