we report 2-mercaptobenzothiazole (mbt) and its analogs as a class of new matrices for matrix-assisted laser desorption mass spectrometry (maldi-ms) at 337 nm. mbt has been used successfully for the desorption of proteins up to 100,000 u. a comparison with sinapinic acid and α-cyano-4-hydroxycinnamic acid indicates that mbt provides the same level of sensitivity and resolution, but offers the
antiscorching agent ctp (pvi) (powder) cas 17796-82-6,meanwhile, it has reclaimaion function for rubber materials that have been borne at high temperature or dangerous for scorching. packaging and storage of antiscorching agent ctp (pvi) packed in paper/plastic laminated bag, of 20 or 25 kg net .the products should be stored and transported on pallets in dry and covered places and vehicles.
mbt(m) rubber accelerator: enhancing performance in rubber
mbt(m), also known as 2-mercaptobenzothiazole, is a widely used rubber accelerator that plays a crucial role in the production of rubber products. this article aims to provide an in-depth understanding of mbt(m), its characteristics, its applications in rubber production, its compatibility with other products, and the key factors to consider when commercially procuring mbt(m) for business
zinc 2-mercapto benzothiazole(zmbt,mz) cas no:155-04-4,zinc 2-mercapto benzothiazole (zmbt,mz) accelerator zmbt can be used as natural rubber, general synthetic rubber and latex vulcanization accelerator, its properties are similar to accelerator m, but the promotion effectiveness is slightly weaker.

a novel solid phase extractor for preconcentration of cadmium at ng l(-1) levels has been developed. cadmium ions were retained on a column packed with sulfur powder modified with 2-mercaptobenzothiazole (2-mbt) in the medium of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim]( )pf(6)(-)) ionic liquid.
rubber vulcanization accelerator cbs (cz) manufacturer and supplier,adding an accelerator to the rubber material can activate the vulcanizing agent, thereby accelerating the cross-linking reaction between the vulcanizing agent and rubber molecules, achieving the effect of shortening vulcanization time and reducing vulcanization temperature.the promotion efficiency of rubber vulcanization is an important
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
freudenberg introduces etu-free accelerator for rubber news,freudenberg sealing technologies, one of four business divisions within freudenberg group, has developed an ethylene thioura (etu)-free compound for cross-linking chloroprene rubber. etu is used industry-wide as an accelerator in the vulcanization process. specifically, freudenberg will use the new compound in seals and bellows.
2-mercaptobenzothiazole 99.9% (hplc) in stock others
catalog no.e0184 purity:99.9%. 2-mercaptobenzothiazole (benzothiazole-2-thiol, 2-mbt, mercapto-2-benzothiazole) is an exceptionally potent inhibitor of banana polyphenoloxidase and can significantly delay the onset of substrate oxidation at concentrations as low as 100 nm. 2-mercaptobenzothiazole chemical structure. cas no. 149-30-4.
2 mercaptobenzothiazole an overview sciencedirect topics,in literature (manninen et al., 1996) an acidic hydrolization at room temperature with 2-mercaptobenzoxazol (mbo) as internal standard was described. with the help of urine samples of persons exposed to 2-mbt, the recoveries of different hydrolysis conditions were tested. it turned out that enzymatic hydrolysis yielded up to fourfold higher 2
2 mercaptobenzothiazole an overview sciencedirect topics,2-mercaptobenzothiazole (2-mbt) is mainly used as a vulcanisation accelerator in the production of rubber. other applications are as a fungicide in paints and varnishes as well as for the external treatment of animals. because of its manifold applications in consumer products, for example in soothers, exposure of the general population to 2-mbt
- Is 2-mbt a vulcanization accelerator?
- 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).
- Who is exposed to MBT?
- In the studies evaluated by the IARC Monographs Working Group, exposure to high amounts of MBT in humans occurred in workers in the chemical industry, but workers in the rubber or tyre-manufacturing industries may also be exposed to MBT.
- Can MBT cause cancer?
- The IARC Monographs evaluation is a hazard classification. It indicates the strength of the evidence that MBT can cause cancer. The probability of developing a cancer will depend on factors such as the type and extent of exposure and the strength of the effect of the agent.
- Does MBT cause bladder cancer?
- An increase in the incidence of bladder cancer was observed in two studies of chemical plant workers exposed to high amounts of MBT. In studies in experimental animals, an increase in the incidence of tumours was observed in rats and mice exposed orally to MBT. What does the classification mean?
