What is The Mechanism of Action of Accelerator MBTS 120-78-5 As An Accelerator in Rubber Compounding?

 

 

The mechanism of action of accelerator MBTS in rubber mixing involves activating and promoting the vulcanization process of rubber. Accelerator MBTS (2,2'-Dithiobis(benzothiazole)) acts as a secondary accelerator, meaning it works in conjunction with the primary accelerator to speed up the cure rate of the rubber. During the vulcanization process, sulfur bridges form between adjacent rubber chains, thereby increasing the strength, stiffness and other properties of the rubber. Accelerator MBTS works through its sulfur bridges, which react with free sulfur in the rubber compound to form a more stable cross-linked structure. This results in faster cross-linking and faster curing, resulting in a more elastic and durable rubber product. The accelerator MBTS also enhances the tensile strength, tear strength and aging resistance of rubber compounds. It also has better heat resistance, lower compression set and improved bonding properties.

Accelerator MBTS can be used both as a primary accelerator and as a secondary accelerator depending on the rubber compound and application requirements. It is commonly used as a secondary accelerator when combined with a primary accelerator such as MBT or CBS, but it can also be used as a primary accelerator in some rubber compounds. The selection and dosage of accelerator MBTS will depend on various factors including rubber type, cure system, processing conditions, and end-use requirements.

How is Accelerator MBTS 120-78-5 Stored?

Accelerator MBTS, also known as 2-mercaptobenzothiazole disulfide, is typically stored in a cool, dry, and well-ventilated area away from sources of heat and ignition. The storage temperature should be maintained between 5 degree to 35 degree (41 degree F to 95 degree F), and the relative humidity should be less than 80%. It is recommended to use the product within its shelf life to ensure quality and efficacy. It should be kept in its original container, tightly sealed, and labeled properly with the chemical name, composition, and hazard warnings. It is recommended to store the accelerator MBTS in a separate area, where incompatible substances or materials that may react with it are not present. Additionally, proper handling and personal protective equipment should be used when working with this chemical, as it can cause skin and eye irritation, and may be harmful if ingested or inhaled.

How Does The Dosage of Accelerator MBTS 120-78-5 Affect Its Performance in Rubber Processing?

It is effective in promoting the crosslinking of rubber molecules and improving the physical properties of the final product. The dosage of accelerator MBTS can affect the vulcanization rate and efficiency of the rubber compound. At low dosages, the rate of vulcanization may be slower, and the final product may be softer with lower tensile strength and elongation. For high dosages, the rate of vulcanization may be too fast leading to over-cure, resulting in reduced mechanical properties, such as reduced flexibility and impaired tear resistance. It is essential to optimize the dosage of accelerator MBTS to achieve the desired physical properties of the rubber compound while minimizing any associated negative effects.

Excessive use of accelerator MBTS can lead to over-curing and may cause blistering and voids in the rubber compound. Therefore, it is important to carefully control the amount of accelerator MBTS used in rubber formulations to achieve optimal curing characteristics and physical properties.
