OBTS is an excellent after-effect accelerator mainly used in the manufacture of tires. It is a vulcanizing accelerator with delayed reaction and short cure time. OBTS is widely used in NR, IR, SBR, NBR and EPDM and can be used alone or with other vulcanization accelerators such as thiurams, guanidines and dithiocarbamates to improve activity.
