rubber accelerators: cbs, tmtd, mbt, mbts price,rubber accelerators like cbs, tmtd, and mbt are chemicals used in the rubber industry to speed up the vulcanization process. cbs is a primary accelerator, tmtd is a secondary accelerator, and mbt is a fast-acting accelerator. they improve the processing and physical properties of rubber products, commonly used in tire production.
rubber accelerator tmtd-ot powder manufacturer price
tmtd is a very active, sulfur-bearing, non-discoloring rubber accelerator for use in nr, sbr, nbr, epdm as well as other rubber elastomers and blends. for most compounding applications, tmtd requires the addition of zinc oxide and fatty acid for effective use. sulfur is not required but is often used.
chemical rubber accelerator tmtd - 137-26-8 powder.suitable for natural and synthetic rubber and latex, being a good secondary accelerator of kinds of thiazole, it is used with other accelerators to the continuous vulcanization. tmtd is regulated for use in articles in contact with food as specified under fda 21 cfr177.2600, 175.105 and under bgvv xxi, categories 1-4 and “sonderkategorie”.

- What is TMTD used for?
- 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. It can be used: In conjunction with accelerators such as mercaptobenzothiazole (0.25 – 0.5 TMTD on the weight of the gum).
- What is accelerator TMTD?
- Accelerator TMTD is also available in a pellet form and micro granules (MG) to reduce dusting. TMTD contains 13% available sulfur. Improved scorch resistance can be obtained in TMTD stocks by the use of the thiazole or sulfenamide accelerators as a primary accelerators. TMTD is an off-white to light gray in color.
- Does TMTD require sulfur?
- Sulfur is not required but is often used. It is widely used as a primary accelerator for curing systems requiring very low or no sulfur. TMTD is often used to activate thiazole or sulfenamide cure systems. Accelerator TMTD is also available in a pellet form and micro granules (MG) to reduce dusting. TMTD contains 13% available sulfur.
- What is rhenocure TMTD/C?
- Rhenocure® TMTD/C is a non-discoloring ultra accelerator and sulfur donor suitable for conventional curing processes. Rhenocure® TMTD/C is a non-discoloring ultra accelerator suitable for conventional curing processes (press, steam and hot air). It can be used in NR, IR, BR, SBR, NBR, CR and EPDM.
- Does rhenocure TMTD/C decompose?
- Rhenocure® TMTD/C is easy to disperse in rubber compounds. There is no risk of decomposition during mixing in the absence of sulfur. The presence of zinc oxide is essential for the correct functioning of Rhenocure® TMTD/C. In most applications stearic acid is needed as well. Rhenocure® TMTD/C does not cause sensitization of latex compounds.
- How to store dimacit TMTD?
- Inorganic acids break down Dimacit TMTD into carbon disulfide and hydrogen sulphide. Store in dry well-ventilated place away from foodstuffs. No reduction in the assay of the active substance has been observed after storage for 2 years in the original packing under normal conditions. Protect against acids and substances liberating acids.
