Rubber Accelerator TBzTD_OKCHEM
Developed to replace thiurams such as TMTD. The dibenzylnitrosamine is not carcinogenic according to published literature. Be a fast curing primary or secondary accelerator in NR, SBR and NBR applications. Be safer to process, provide longer scorching times than TMTD. Sometimes used as retarder in the vulcanization of polychloroprene rubber.

Sulfamic acid 5329-14-6 richest-rubber
Sulfamic acid 5329-14-6. Type.: Cleaning agent, Curing Agent, Flame Retardant. (2) Sulfamic Acid is used as an herbicide, fine retardant, depurative of metal, pottery and porcelain. (3) Sulfamic Acid is used as softener and bleacher of paper and textile.
CAS# 137-26-8. WESTCO™ TMTD is the most widely used among ultra-accelerators in natural and synthetic rubber; acts as a retarder for CR; an effective accelerator for low temperature cures. Rubber curing accelerator with super anti-scorching and short curing time features. Used in manufacture of tires, shoes, tubes, cable, etc.
Curing characteristics, mechanical and thermal properties
Aug 27, 2014· The lowest t90 value (2.9 min) and the highest CRI value (58.8 min-1) were observed for rubber compound cured with conventional curing system (accelerator/sulfur 1:2) based on TMTD accelerator, while the highest t90 (16.1 min) and the lowest CRI values (7.1 min-1) were observed for compound containing DPG accelerator.
TBTD can be used as super accelerator and curing agent for natural and synthetic rubber, the effective sulfur content is 7.5%, the best curing temperature is 95-110℃. It is often used in low temperature vulcanizates due to its larger solubility in organic solvent, could be used for sulphur-free rubber together with accelerator TMTD, the aging

- 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. 144 0.30 0.40 1.43 144 ---- 0.50
- What are the different types of rubber accelerators?
- There are several types of rubber accelerators, classified based on their composition and the type of rubber they’re used with. The most common ones include Thiazoles (MBT, MBTS, and ZMBT), Sulfenamides (CBS, TBBS, NOBS, etc.), Guanidines (D, DOTG), Thiurams (TMTM, TMTD, DPTT), and Dithiocarbamates (ZDEC, ZDBC, ZDMC).
- What is TMTD used for?
- 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. 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.
- What is a rubber accelerator?
- Rubber accelerators are substances that increase the speed of vulcanization, a process where rubber becomes more durable through the addition of sulfur at high temperatures. They play a pivotal role in reducing the curing time and improving the efficiency of the vulcanization process.
- What is a thiuram accelerator?
- Thiurams are ultra-fast accelerators used predominantly in the manufacture of cables, wires, and other rubber goods that require heat resistance. They offer excellent scorch safety during the vulcanization process and are often used with other accelerators to control the rate of vulcanization.
- Are there alternatives to rubber accelerators?
- For individuals who have an allergic reaction to rubber accelerators, alternatives include using products made from synthetic rubber or rubber products that are free of accelerators. It’s also possible to use products made with alternative accelerators that don’t cause an allergic reaction in the individual.
