What is Rubber Accelerator
Rubber Accelerator is a type of chemical additive used in the production of rubber materials. It is designed to enhance the vulcanization process, which is the cross-linking of rubber molecules that gives the material its final properties. Rubber Accelerator can be found in a wide range of products, including tires, hoses, belts, and other rubber goods. It is typically added to the rubber compound before vulcanization and helps to speed up the vulcanization process, reducing processing time and energy requirements. Rubber Accelerator also affects the physical properties of the final rubber product, such as tensile strength, Shore hardness, flexural modulus, tear strength, and fatigue resistance.
Advantages of Rubber Accelerator
Improved Processing Time
One of the primary advantages of using rubber accelerators is that they can significantly improve the processing time of rubber. Without accelerators, the vulcanization process can take several hours or even days. However, with the use of accelerators, the time required for vulcanization can be reduced to just a few minutes, allowing for a more efficient production process.
Enhanced Physical Properties
Accelerators not only speed up the vulcanization process but also enhance the physical properties of the rubber. They can improve the elasticity, strength, and durability of the rubber, making it more suitable for various applications. This is particularly important for applications where the rubber is subjected to high stress or temperature, such as in the automotive and construction industries.
Cost-Effective
The use of rubber accelerators can also be cost-effective. By improving the efficiency of the production process, accelerators can help reduce the overall cost of production. Additionally, the improved physical properties of the rubber can also increase the lifespan of the end product, reducing the need for frequent replacements and saving money in the long run.
Versatility
Rubber accelerators are versatile and can be used with various types of rubber, including natural rubber and synthetic rubber. This makes them a useful tool for manufacturers who produce a wide range of products made from different types of rubber.
Customization
Accelerators can also be customized to suit the specific needs of a production process. Different types of accelerators can be used to achieve different results, such as improving the processing time, enhancing the physical properties of the rubber, or reducing the overall cost of production.
Environmental Considerations
Finally, some rubber accelerators are designed to be more environmentally friendly. These accelerators can reduce the amount of waste produced during the production process and have less of an impact on the environment.

What Are the Main Components of Rubber Accelerator
Rubber accelerator is a kind of rubber additive, which can promote the vulcanization reaction of rubber and shorten the vulcanization time. The main components of rubber accelerator are sulfur, thiuram, dithiocarbamate, mercaptobenzothiazole and their derivatives. These components can interact with sulfur in rubber to form sulfur-containing polymers, which can accelerate the vulcanization reaction of rubber. Some rubber accelerators also contain anti-aging agent, plasticizer and other additives to improve the performance of rubber products.
What Are the Different Types of Rubber Accelerators Available
Primary Accelerators
Also known as sulfenamides, primary accelerators are the most commonly used type of rubber accelerator. They are highly effective at promoting vulcanization and are typically used in combination with secondary accelerators to achieve the desired properties. Examples of primary accelerators include N-cyclohexyl-2-benzothiazolesulfenamide (CBS), N-tert-butyl-2-benzothiazolesulfenamide (TBBS), and N,N-dicyclohexyl-2-benzothiazolesulfenamide (DCBS).
Secondary Accelerators
Secondary accelerators are used in combination with primary accelerators to enhance the overall performance of the rubber compound. They help to improve the processing characteristics of the rubber and can also provide additional benefits such as improved aging resistance and heat resistance. Examples of secondary accelerators include thiurams, such as tetramethylthiuram disulfide (TMTD), and guanidines, such as diphenylguanidine (DPG).
Impact Accelerators
Impact accelerators are used to improve the impact resistance of rubber compounds. They are typically used in applications where the rubber is subjected to high stress or impact, such as in the production of tires and conveyor belts. Examples of impact accelerators include thiazoles, such as 2,2'-dithiobisbenzothiazole (MBT), and thioureas, such as ethylbenzothiazolyl-2-sulphenamide (EBS).
Delayed Action Accelerators
Delayed action accelerators are used in applications where a longer lag time is required before vulcanization begins. They are typically used in combination with primary and secondary accelerators and can provide additional benefits such as improved aging resistance and heat resistance. Examples of delayed action accelerators include thiophanates, such as thiophanate-methyl (TMTM), and dithiocarbamates, such as zinc dimethyldithiocarbamate (ZDEC).
Non-Sulfur Accelerators
Non-sulfur accelerators are an alternative to sulfur-based accelerators and are used in applications where the use of sulfur is not desired or not possible. They are typically more expensive than sulfur-based accelerators but can offer improved performance in certain applications. Examples of non-sulfur accelerators include guanidines, such as diphenylguanidine (DPG), and thioureas, such as ethylene thiourea (ETU).
What Is the Difference Between Primary and Secondary Rubber Accelerators
Primary and secondary Rubber Accelerators are two types of chemical additives used in the production of rubber materials. They have different chemical structures and properties, and their functions and application methods are also different.
Primary Rubber Accelerators, also known as vulcanization accelerators, are directly added into the rubber compound before vulcanization. They can promote the vulcanization reaction of rubber and shorten the vulcanization time. Typical primary Rubber Accelerators include guanidine, thiourea, and their derivatives.
Secondary Rubber Accelerators, also known as vulcanization accelerator activators, do not have vulcanization acceleration function by themselves, but can activate the vulcanization accelerator and enhance its vulcanization acceleration effect. Typical secondary Rubber Accelerators include stearic acid, oleic acid, and their metal salts.
The use of secondary Rubber Accelerators can further enhance the vulcanization effect of primary Rubber Accelerators, but also make the vulcanization process more sensitive to temperature and pressure. Therefore, when using secondary Rubber Accelerators, attention should be paid to the control of processing conditions to avoid premature vulcanization and other problems.
