YLSCH-RBB® Accelerator CBS-80 (N-cyclohexyl-2-benzothiazole sulfenamide, referred to as CBS or CZ) is a commonly used accelerator for rubber vulcanization. It has the dual characteristics of delayed vulcanization and rapid vulcanization, and is an important additive in the vulcanization process of natural rubber and synthetic rubber. The following is a detailed introduction to the accelerator CBS-80:

1. Basic Information

Chemical Name: N-cyclohexyl-2-benzothiazole sulfenamide

Chemical Formula: C13H16N2S2

CAS number: 95-33-0

Appearance: light yellow or light gray granules

Purity: CBS-80 means it contains approximately 80% active ingredient, mixed with an inert carrier for easy handling and dispersion

2. Features and functions

Delayed vulcanization: YLSCH-RBB®CBS-80 can delay the start of the vulcanization reaction during rubber processing, allowing the rubber to have a longer operating time (scorch time) and reducing the risk of early vulcanization.

Rapid vulcanization: Once vulcanization begins, CBS-80 can significantly speed up the vulcanization reaction and improve vulcanization efficiency.

Improve rubber properties: Improve the physical and mechanical properties of rubber, such as tensile strength, tear resistance and wear resistance; improve the aging resistance of rubber and extend the service life of rubber products.

Low heat generation: Suitable for rubber products with large dynamic loads, such as automobile tires, to reduce the heat generation of rubber during use, lower the operating temperature of the tires, and improve their durability and safety.

3. Application fields

Auto Tires: Improve wear resistance, tear resistance and dynamic performance, reduce heat generation.

Industrial rubber products:including hoses, tapes, seals, etc., to improve mechanical properties and aging resistance.

Rubber Shoes: Improve wear resistance and comfort.

Other rubber products: such as rubber floors, sports ground floors, etc., to improve vulcanization speed and product performance.

4.Operations and Security

Usage: The optimal usage amount and method need to be determined according to the specific production process and rubber formula. Usually, CBS-80 is used together with other vulcanizing agents and additives to achieve the best results.

Safety Precautions: Pay attention to safety when operating, avoid direct contact with skin and eyes, and ensure to operate in a well-ventilated environment.

The accelerator CBS-80 plays an important role in accelerating vulcanization in the rubber industry. It can significantly increase the vulcanization speed and efficiency and improve the performance of rubber. Its dual characteristics make it widely used in the production of various rubber products, especially in applications that have strict requirements on operating time and vulcanization efficiency.
