    TBzTD: a secondary accelerator for stable crosslink systems in tire

    Semi-efficient vulcanization systems generally consist of higher levels of a primary accelerator, a sulfur donor and lower levels of sulfur. Commonly employed primary accelerators in the tire industry are 2-Mercaptobenzothiazole (MBT) and delayed action sulfenamides (MBS, TBBS or CBS) in the part level range from 1.0 to 2.0 phr.
