MBTS Rubber: Properties, Uses, and Benefits

19/01/2024

MBTS rubber is a widely used rubber accelerator that plays a crucial role in the production of rubber products. MBTS stands for 2,2′-Dibenzothiazole Disulfide, and it is a general-purpose accelerator for sulfur cures. It is very active above 142°C (287°F) and is a non-staining primary thiazole accelerator for use in natural and synthetic rubbers.

MBTS Rubber

MBTS rubber is used in tire manufacturing, shoe soles, and other rubber products. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithiocarbamates, and guanidines. MBTS is used as a secondary accelerator in combination with other accelerators to improve the speed of vulcanization and the properties of the vulcanizate.

MBTS Rubber Overview

Chemical Composition

MBTS (2,2′-Dibenzothiazole Disulfide) is a sulfur-based organic compound with the chemical formula C14H8N2S4. It is a yellowish powder, soluble in benzene, chloroform, and carbon disulfide, and almost insoluble in water. MBTS is a member of the benzothiazole family of chemicals, and it is commonly used as a rubber accelerator.

Properties and Characteristics

MBTS is a versatile accelerator that can be used in a wide range of rubber products. It can be used alone or in combination with other accelerators, such as thiazoles, thiurams, and sulfenamides. MBTS is particularly effective in the vulcanization of natural rubber and synthetic rubbers, such as SBR, NBR, and EPDM.

MBTS has a number of desirable properties, including fast curing speed, high curing activity, good scorch safety, and excellent aging resistance. It is also relatively non-toxic, making it a popular choice for use in food contact applications.

However, MBTS does have some limitations. For example, it can cause discoloration in certain rubber compounds, and it may not be suitable for use in applications that require high levels of heat resistance. Additionally, MBTS can be sensitive to over-curing, which can lead to decreased physical properties in the finished product.

Overall, MBTS is a widely used rubber accelerator with a number of desirable properties. Its versatility and effectiveness make it a popular choice for use in a variety of rubber products.

Production Process

MBTS rubber is produced through a series of steps that involve the acquisition of raw materials, mixing and compounding, shaping, and vulcanization. This section will provide an overview of each of these steps.

Raw Material Acquisition

The first step in the production of MBTS rubber is the acquisition of the raw materials. Raw materials used in the production of MBTS rubber include 2-mercaptobenzothiazole (MBT), sulfur, and zinc oxide. These raw materials are acquired from reputable suppliers to ensure that they meet the required quality standards.

Mixing and Compounding

Once the raw materials have been acquired, they are mixed and compounded in a process that involves the use of specialized equipment. The mixing process involves the use of a Banbury mixer, which is a machine that is used to mix and compound rubber. The Banbury mixer is used to mix the raw materials at high temperatures and pressures to ensure that they are well blended.

Shaping and Vulcanization

After the mixing and compounding process, the resulting compound is shaped into the desired form. The shaping process involves the use of specialized equipment such as extruders and presses. The shaped rubber is then subjected to vulcanization, which is a process that involves the use of heat and pressure to enhance the properties of the rubber.

In summary, the production of MBTS rubber involves the acquisition of raw materials, mixing and compounding, shaping, and vulcanization. Each of these steps is critical in ensuring that the final product meets the required quality standards.
