[News & Trends]:The difference between accelerator CZ and CBS: Choose the rubber accelerator that suits you best

Promoters are indispensable additives in rubber production, which can promote the vulcanization process and improve the physical properties of rubber products. Among numerous accelerators, CZ and CBS are commonly used and play important roles in rubber production. So, what is the difference between promoter CZ and CBS? Now let's take a closer look


The chemical composition of promoter CZ and CBS is different. The chemical name of promoter CZ is N-cyclohexyl-2-phenylphenylformamide, while the chemical name of CBS is N-hydroxyphenylorthoformamide. From a chemical structure perspective, there are differences in the molecular structures of CZ and CBS, which also leads to their different modes of action and effects in the vulcanization reaction


Promoters CZ and CBS have different applicability to different types of rubber. CZ is mainly suitable for nitrile rubber and vulcanized nitrile rubber, while CBS is more suitable for butyl rubber, natural rubber, and styrene butadiene rubber. Therefore, when selecting accelerators, it is necessary to choose according to the type of rubber in order to achieve the desired vulcanization effect


In addition, the vulcanization rate and activity of the promoter CZ and CBS are also different. Generally speaking, CZ has a slower vulcanization rate and lower vulcanization activity, making it suitable for rubber products that require extended vulcanization time. CBS has a fast vulcanization speed and high vulcanization activity, making it suitable for rubber products that require high vulcanization speed


There are also differences in the physical properties and heat resistance of the accelerator CZ and CBS after vulcanization. CZ vulcanized rubber products have good tensile strength and heat resistance, suitable for rubber products that require high strength and heat resistance. After CBS vulcanization, rubber products have good elasticity and wear resistance, suitable for rubber products that require good elasticity and wear resistance


In summary, there are significant differences between the promoter CZ and CBS in terms of chemical composition, applicability, vulcanization rate, and physical properties. When selecting accelerators, it is necessary to comprehensively consider the type of rubber, vulcanization requirements, and physical performance requirements in order to choose a suitable accelerator for oneself. I hope the introduction in this article is helpful to you and can help you better choose and apply rubber accelerators.
