in these samples free mbt (without hydrolysis) was also measured (table 5). free mbt was detected in the range 1 137 μg l −1 ( 1 54 μg g −1 creatinine). because the samples were frozen until analytical determination, significant unintended hydrolysis of mbt during the storage and work-up procedure is unlikely and the fraction of non

2 mercaptobenzothiazole an overview sciencedirect topics
2-mbt is used as a vulcanization accelerator especially in rubber products like car tires, cables, seals, shoes, rubber gloves and toys (baua, 2001; bfr, 2008). therefore, a general possible exposure of the population to 2-mbt can be supposed. fukuoka and tanaka suggested the metabolism pattern in rats (fukuoka et al., 1995).
mercaptobenzothiazole rubber accelerator,mercaptobenzothiazole. except where otherwise noted, data are given for materials in their standard state (at 25 °c [77 °f], 100 kpa). 2-mercaptobenzothiazole is an organosulfur compound with the formula c6h4(nh)sc=s. a white solid, it is used in the sulfur vulcanization of rubber.

optimization of accelerators on the properties of natural,this is followed by astm d 2240 93. the accelerator type strongly influences cure characteristics. the effects of accelerators on s′m l and s′m h are summarized in table 2. the s′m l of tbbs, cbs, tmtd, and mbt accelerated nr/w-epdm blends were almost similar. accelerator type did not influence the s′m l value.
- 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.
- Is MBT a vulcanization accelerator?
- As a vulcanization accelerator in the rubber industry, MBT may be discharged into the atmosphere in the form of particles during the processing of substances. MBT emission in the air around workplaces has been reported with older, eastern European plants; however, no quantitative data are available.
- Is MBT a sensitiser?
- MBT is a potent contact allergen which is considered to be the main allergen involved in rubber allergy. MBT was shown to be a sensitiser in a human maximisation test. In several large studies of patients from various countries, 2-5% of the study population exhibited sensitisation to MBT.
- What is the maximum acceptable toxicant concentration (MATC) of 2 mercaptobenzothiazole (MBT)?
- The mean weight at the 380 ug/L level was 1.1582 g which was significantly reduced as compared to controls. The Maximum Acceptable Toxicant Concentration (MATC) was estimated to be greater than 41 ug/L and less than 78 ug/L.
