synergistic combination of 2-mercaptobenzothiazole (mbt)
in this study, we developed a combination accelerator system to synergistically improve the vulcanizing activity of 2-marcapto benzothiazole (mbt) with different nitrosamine-safe thiuram disulfides (tds), namely, bis- (n-benzyl piperazino) thiuram disulfide (bptd), bis- (n-phenyl piperazino) thiuram disulfide (pptd), and bis- (n-ethyl
rapid and sensitive lc ms ms determination of 2,2-mercaptobenzothiazole (mbt) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. given its wide use in household articles and industrial rubber products it has a high potential to migrate into the environment.
accelerators for tires and rubber products,an accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency.
- What is 2-Mercaptobenzothiazole (MBT) vulcanization accelerator?
- 2-Mercaptobenzothiazole (MBT) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. Given its wide use in household articles and industrial rubber products it has a high potential to migrate into the environment. Humans can be exposed by dermal, oral, or inhalative routes.
