Semi ultra fast accelerators for NR, BR, SBR and other highly unsaturated diene rubbers, Thiazole accelerators offer good tensile and resilience properties when used in combination with booster accelerators on a compromise of scorch and reversion resistance.

Fast delayed action accelerators for NR, BR, SBR and other sulphur/sulphur donor cured diene rubbers. They offer excellent scorch safety during the processing of rubber compounds. They impart good modulus, tensile strength, resilience and flex fatigue resistance in comparison with thiazole accelerators. Activities of Sulphenamide accelerators may be further boosted by using small dosages of thiuram class of accelerators.

Thiuram Ultra fast accelerators for NR, BR, SBR and highly unsaturated diene rubbers, these normally are used as secondary accelerators in combination with sulphenamide or thiazole class of accelerators. However, they are most preferred primary accelerators for sulphur cured unsaturated rubbers like butyl and EPDM. It can be used as sulphur donor in case of EV cure of diene rubbers.

Dithiocarbamates They are ultra fast primary accelerators for NR latex based compounds. They exhibit scorching tendency, faster cure rate and higher cross link density.

Used as a secondary accelerator with sulfenamides and thiazoles in rubber and as secondary gelling agent in foam rubber

Used to increase the speed of vulcanization.
