Product description. TMTD is widely used in rubber processing as an ultra accelerator for low-temperature cures, either alone or as an activator for other accelerators, chiefly the thiazoles. With sulphur in conjunction with zinc oxide and fatty acid as activators (0.1 1% TMTD on the weight of the gum), In conjunction with accelerators such

CAS : 97-74-5. EINECS : 202-605-7. PROPERTIES: NURCHEM TMTM-80 is generally used as a secondary accelerator or as a booster for sulphenamides to achieve faster cure rates. It can be used as a booster for thiazoles and guanidines in general purpose elastomers as well. Its main application is in NBR in combination with MBT or MBTS where it acts
- What is accelerator TmTm?
- Accelerator TMTM is a non-staining, non-discoloring, fast curing secondary accelerator with excellent storage stability. It can be used alone or in combination with other accelerators in NR, SBR, NBR, Butyls, Neoprene and Reclaim Rubber. Appearance . . . . . . . . . . . . . . Yellow powder & pellets
- 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.
- 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.
- 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.
- 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.
- Is accelerator TmTm a thiuram disulfide?
- Accelerator TMTM provides very good processing safety while still allowing for high cure activity. Unlike the thiuram disulfides, the monosulfide TMTM will not produce cures in the absence of added elemental sulfur. Accelerator TMTM is also available as Akroform® TMTM-80.
