Tetramethylthiuram disulfide Big Chemical Encyclopedia
Among these, Vulkacit CRV is the most widely used. An accelerator is ordinarily used ia combination with a retarder to control premature cross-linking. Tetramethylthiuram disulfide [137-26-8] is ordinarily used for this purpose when the accelerator is either ethylenethiourea [96-45-7] or a thia2o1idinethione.

- What is TmTm rubber accelerator?
- TMTM is a thiuram disulfide compound and is commonly used as an accelerator in the production of rubber products such as tires, hoses, and belts. The primary function of TMTM rubber accelerator is to increase the rate of vulcanization of the rubber, which improves the physical properties of the finished product.
- Is TmTm rubber accelerator harmful?
- Exposure to TMTM rubber accelerator can pose health risks. Prolonged or repeated exposure to the substance can cause skin irritation and sensitization, as well as respiratory irritation. In addition, it may cause eye irritation or damage and can be harmful if ingested. Exposure to TMTM rubber accelerator may also pose environmental risks.
- How does TmTm work?
- It is particularly effective in accelerating the vulcanization of natural rubber and synthetic rubbers such as Zinc, SBR, NBR, and EPDM. TMTM is also known for its ability to improve the heat resistance, aging resistance, and compression set of rubber products.
- Why is TmTm important in rubber vulcanization?
- TMTM is an essential component in the vulcanization process of rubber. It acts as a secondary accelerator, enhancing the crosslinking reaction between sulfur and rubber molecules. This results in improved mechanical properties such as tensile strength, elongation at break, and tear resistance.
- What is the production process of TmTm accelerator?
- The production process of TMTM accelerator starts with the sourcing of raw materials. The primary raw materials used in the production process include tetramethylthiuram monosulfide (TMTM), sulfur, and carbon disulfide. These materials are typically sourced from reputable suppliers to ensure their quality and consistency.
- Is TmTm suitable for low sulfur vulcanization systems?
- TMTM is particularly suitable for low sulfur vulcanization systems. In summary, TMTM is a sulfur-based rubber accelerator with a melting point of 104-107°C and a molecular weight of 208.4 g/mol. It is soluble in chloroform, benzene, and acetone, and insoluble in water.
