Accelerator is an indispensable additive in rubber production, which can promote the vulcanization process and improve the physical properties of rubber products. Among the many accelerators, CZ and CBS are the two commonly used, and they play an important role in rubber production. So, what is the difference between CZ and CBS? Let's take a closer look. The

accelerators CZ and CBS differ in chemical composition. The chemical name of the accelerator CZ is N-cyclohexyl-2-phenylphenylformamide, while the chemical name of CBS is N-hydroxyphenyl-o-formamide. From the chemical structure point of view, there are differences in the molecular structure of CZ and CBS, which also leads to their role in the vulcanization reaction and the effect is different.

accelerators CZ and CBS have different applicability to different kinds 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 the accelerator, it is necessary to select the accelerator according to the type of rubber so as to achieve the desired vulcanization effect.

In addition, the vulcanization speed and vulcanization activity of the accelerators CZ and CBS are also different. Generally speaking, the curing speed of CZ is slow and the curing activity is low, which is suitable for rubber products that need to extend the curing time. The CBS vulcanization speed is faster and the vulcanization activity is higher, which is suitable for rubber products with higher requirements for vulcanization speed. There are also differences in the physical properties and heat resistance of

accelerators CZ and CBS after vulcanization. CZ vulcanized rubber products have good tensile strength and heat resistance, and are suitable for rubber products requiring high strength and heat resistance. The CBS vulcanized rubber products have good elasticity and wear resistance, and are suitable for rubber products that require good elasticity and wear resistance.

To sum up, there are obvious differences between CZ and CBS in chemical composition, applicability, curing speed and physical properties. When selecting an accelerator, it is necessary to comprehensively consider the type of rubber, vulcanization requirements and physical performance requirements to choose the accelerator that suits you. I hope the introduction of this article is helpful to you and can help you better select and apply rubber accelerators.
