application: accelerator dcbs (dz) possesses the best anti-scorching quality of sulfenamide type accelerators. its anti-scorching quality and processing safety in natural rubber are better than that of dibs. mainly used in manufacture of tires, rubber belts and shock absorbers.
occurrence of polymer additives 1,3-diphenylguanidine (dpg),,while much of the recent concern related to polymer additives such as dpg and 6ppd has been closely associated with tire rubber related sources, our findings suggest that additional sources might contribute to the presence of polymer additives in drinking water.

rubber accelerators crossland chemicals,cas no. 4979-32-2. performance: soluble in benzene, dichloromethane, carbontetrachloride, petrol, ethyl acetate, ethanol,insoluble in water. application: dcbs is a delayed accelerator of good dispersion quality in rubber, the scorching duration is long, which could improve the safety of operation.
rubber accelerator dcbs with high quality,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.
- 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.
- Is DCBS a toxicity hazard?
- The acute toxicity of N,N-dicyclohexyl-2-benzotazothiazolesulfenamide (DCBS) is low. The oral LD50 in rats is greater than 1,000 mg/kg and the dermal LD50 in rabbits is more than 2,000 mg/kg. This chemical is moderately irritating to skin and slightly irritating to eyes but no sensitizing to skin.
- Does DCBS have a high bioaccumulation potential?
- DCBS is a white powder with a water solubility of 1.9 x 10-3 mg/L at 25 °C, a melting point of 99 °C at 1013 hPa and a vapour pressure of < 7.0 x 10-5 Pa at 100 °C. A measured log Kow value of >4.8 suggests that this chemical is suspected to have a high bioaccumulation potential.
- Is DCBS genotoxic in vivo?
- The weight of evidence suggests this chemical may not be genotoxic in vivo. DCBS is a white powder with a water solubility of 1.9 x 10-3 mg/L at 25 °C, a melting point of 99 °C at 1013 hPa and a vapour pressure of < 7.0 x 10-5 Pa at 100 °C.
