if the confluency of healthy cells is greater than 80 %, it is taken as non-cytotoxic [32, 33]. thus the mtt assay showed that the natural rubber vulcanizates containing dcbs and dbbs are safe (non-cytotoxic). iv. conclusions natural rubber vulcanizates containing dcbs or dbbs as single accelerator system show very good scorch safety.
non-regulated accelerator (dcbs/dbbs) incorporated natural,the vulcanizates prepared using non-regulated nitrosamine generating accelerators are reported as noncarcinogenic. efficient vulcanization system containing nonregulated single accelerator (either n, n-dicyclohexyl-2- benzothiazolesulfenamide (dcbs) or n,n-dibenzyl-2- benzothiazolesulfenamide (dbbs)) was used for the preparation of safe natural rubber vulcanizates.

(pdf) non-regulated accelerator (dcbs/dbbs) incorporated
the natural rubber formulations based on safe single accelerator (either dcbs or dbbs) and their combination with the non-regulated tbztd have been used for the studies presented in this paper. ii. experimental a. materials natural rubber (isnr-5) used in this study was obtained from the rubber research institute of india (kottayam, kerala, india).
vulcanization accelerators chemical rubber,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. accelerator also decreases the quantity of sulphur necessary for vulcanizationand thus improving 'aged'
- What is a DCBS accelerator?
- Accelerator DCBS is a delayed action sulfenamide accelerator for use in natural and synthetic rubbers. It is recommended for applications where exceptionally long flow times are required. DCBS is particularly suitable for rubber goods subjected to high dynamic stresses. It is a primary accelerator
- Is DCBS a sulfonamide accelerator?
- Soluble in acetone organic liquids, including fats and oils, insoluble in water. DCBS is a sulfonamide accelerator with excellent anti-scorching property and delayed onset of cure. It is compatible with natural and synthetic rubbers. Suitable for radial ply tyre, rubber belts and shock absorber, etc. Particularly it produces good adhesion to metal.
- What is DCBS used for?
- DCBS is very effective for use in thick cross-section molded articles. It also is finds application where high processing temperatures are encountered or delayed cures are needed for optimum adhesion. favorable. DCBS is also employed in conveyor belts, driving belts, shock absorbers, mountings and
- Which sulfenamide accelerator is best for rubber goods?
- DCBS is particularly suitable for rubber goods subjected to high dynamic stresses. It is a primary accelerator which can be used alone or in combination with many secondary accelerators. DCBS offers the best scorch resistance of all commonly used sulfenamide accelerators.
- What are accelerators used for?
- Accelerators are materials that are added in small amounts to speed up the curing of adhesives. The first accelerators were used in the 19th century. In that period, mostly oxides and hydroxides of inorganic compounds like lead, zinc, magnesium and calcium were brought to use. These days organic compounds are majorly used as accelerators.
- What are the different types of accelerators?
- The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines. Part or all of the sulfur may be replaced by an accelerator that is also a sulfur donor such as a thiuram disulfide.
