rubber accelerator cbs 95-33-0 price
rubber accelerator cbs (cas no. 95-33-0) is a gray-white powder with a slight odor. it is an excellent accelerator for natural rubber, synthetic rubber, and latex. cbs accelerates the vulcanization process, which improves the mechanical properties, stability, and durability of rubber products. cbs is commonly used in the production of tires.
select accelerators for rubbers supplier.accelerator: an accelerator is a material that, when mixed with a catalyst and resin, speeds up the chemical reaction between the catalyst and the resin (usually in the polymerizing of resin or vulcanization of rubbers). accelerators are also known as promoters when used with polyester resins and vulcanizing agents when used with rubbers.
vulcanization and antioxidation effects of accelerator
the curing curves (cz = 0 phr) in fig. 7 display that without any accelerator, the vulcanization reaction of the sbr compound did not occur, while the vulcanization process was improved by the addition of btc (i.e., an increase in the torque of btc/sbr compound). this indicated that btc can indeed act as an accelerator to promote rubber.

- What vulcanizing agent is used in rubber?
- Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
- How vulcanization is used in the rubber industry?
- Almost all useful rubber products have to be a three-dimensionally cross-linked network for displaying stable elasticity. Among various cross-linking reactions, the most widely used in the rubber industry is vulcanization, i.e., cross-linking with sulfur. Vulcanization was first developed by Goodyear in 1839.
- What is the role of fatty acids in vulcanization reaction of rubber?
- Although it is well-known that fatty acids are organic activators that are widely used in the rubber industry, this is the first report on role of fatty acids during the vulcanization reaction of rubber. This basic and important result is useful to better understand the complicated vulcanization reaction of rubber, especially that of NR.
- What are the different types of rubber vulcanizing accelerators?
- W. He, In rubber tire production, three popular types of rubber vulcanizing accelerators exist that are similar in appearance (i.e., 2-mercaptobenzothiazole, 4,4′-dithiodimorpholine, and tetramethyl thiuram monosulfide).
- When was vulcanization invented?
- Vulcanization was first developed by Goodyear in 1839. Since then, additives such as accelerators, activators, and retarders have been developed for the improvement in processability and mechanical properties of rubber products.1–10 Activators have been described as substances that increase the effects of accelerators.
- What determines vulcanization rate?
- The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
