2-mercaptobenzothiazole was determined in urban air partic-ulates for the first time in this study, and its presence in inhalable pm 10 implies that the human exposure to this bio-cide is underestimated. this calls for a revision of the risk assessments of 2-mercaptobenzothiazole exposure to humans which currently is limited to occupational
rubber auxiliary agent mmbi prospector by ul,mmbi is non-discoloring, non-staining antioxidant for all rubbers. it is particularly effective in nbr and epdm. provides very good heat aging and flex protection when used in combination with westco tmq.
occurrence of benzothiazole and its derivates in tire wear
the mass fractions of ∑bts ranged from 46.93 to 215.70 μg/g with an average of 99.32 μg/g in tire debris, from 0.25 to 1.63 μg/g with a median concentration of 0.68 μg/g in tsp, from 10.78 to 55.18 μg/g with a median concentration of 22.03 μg/g in pm 10, and from 7.79 to 109.3 μg/g with a median concentration of 26.62 μg/g in pm 2.5

using benzothiazoles as tracers for tire tread emission
the samples were analyzed for five selected benzothiazoles; 2-hydroxybenzothiazole (ohbt), 2- mercaptobenzothiazole (mbt), 2-aminobenzothiazole (abt), benzothiazole (bt) and 2-methylthiobenzothiazole
zinc dibutyl dithiocarbamate zdbc robinson brothers,used as primary or secondary super accelerator for natural rubber, isoprene rubber, butadiene rubber, nitrile rubber, high resilience rubber, epdm rubber and their latex. similar properties to pz and ez. weaker accelerator for dry rubber than pz and ez.

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.
high quality tbbs accelerator for rubber market analysis: market landscape,our recent report forecasts that the tbbs accelerator for rubber market size is projected to reach approximately usd xx.x billion by 2031, up from usd xx.x billion in 2023. this growth is expected
rubber accelerator 2-mercaptobenzothiazole (mbt)
what is 2-mercaptobenzothiazole? 2-mercaptobenzothiazole (mbt) is an industrial chemical that is used principally in the manufacture of rubber. what were the results of the iarc monographs evaluation of mbt? the working group of volume 115 of the iarc monographs classified mbt as probably carcinogenic to humans (group 2a) based on limited
tire tread wear particles in ambient air-a previously unknown,airborne particulate matter (pm10) sampled at a busy street in stockholm, sweden, contained on average 17 pg/m(3) benzothiazole and 64 pg/m(3) 2-mercaptobenzothiazole, and the total suspended
some industrial chemicals international agency for research,2-mercaptobenzothiazole (wick et al., 2010). a single method has been described for the deter-mination of 2-mercaptobenzothiazole in dietary products (barnes et al., 2003). 1.4 occurrence and exposure due to its use as an accelerant in rubber vulcanization, 2-mercaptobenzothiazole can be found as a contaminant in rubber products.
- What is 2-Mercaptobenzothiazole (MBT)?
- Provided by the Springer Nature SharedIt content-sharing initiative 2-Mercaptobenzothiazole (MBT) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. Given i
- What is the analytical standard for 2-mercaptobenzothiazole?
- The analytical standard 2-mercaptobenzothiazole (99 %) was obtained from Fluka, and the deuterated internal standard 2-mercaptobenzothiazole- (2,4,5,6-d 4) was custom synthesized at IDM (Teltow, Germany). The identification and purity of the deuterated internal standard were confirmed by 1 H-NMR and 13 C-NMR.
