Vulcanization Accelerators
An accelerator is defined as a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber.
Abstract: Thiuram (DPTT, TMTD), thiazole (MBT, MBTS), sulfenamide (CBS, NOBS), and zinc containing thiuram (dithiocarbamate) (ZDBC) type accelerators were added into silica and carbon black filled natural rubber (NR) com-pounds. Their effects on vulcanization time and rate were compared. The vulcanization rate of thiuram type accelerator

Rubber Vulcanizing Accelerator TMTD (TT) Date Posted: 2016-10-26: Updated Date: 2017-01-17 00:59:24: It can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression
Abstract. Compounding mixtures were prepared based on acrylonitrile-butadiene rubber (Krynac 803) to which increasing parts per hundred rubber (pphr) of the following accelerates were added: tetramethyl thiuram disulfur (TMTD in series A 1), tetramethyl thiuram monosulfur (TMTM in series A 2), 2-mercaptobenzothiazole (MBT in series A 3), and 2,2′
