Accelerator: An accelerator is a material that, when mixed with a catalyst and resin, speeds up the chemical reaction between the catalyst and the resin (usually in the polymerizing of resin or vulcanization of rubbers). Accelerators are also known as promoters when used with polyester resins and vulcanizing agents when used with rubbers.
REDUCED ZINC OXIDE LEVELS IN SULPHUR VULCANISATION
The unaccelerated vulcanisation process utilised elemental sulphur at 8 parts per 100 parts of rubber (phr) and required a temperature of 142°C for 6 hours. By adding a few parts of organic accelerator, the vulcanisation time was reduced enormously.3,5 Further it was found that zinc oxide (ZnO) acts as a so-called
The global vulcanization accelerators market was valued at ~US$ 1.4 Bn in 2018. The vulcanization accelerators market is anticipated to grow at a CAGR of ~4.0% during the forecast period of 2019-2029. For the vulcanization accelerators market, East Asia is estimated to be a prominent region as it contributed a high revenue share in 2018. Nearly 45% of the

PRODUCTS COMPONENT APPEARANCE APPLICATION; CBS-80: N-cyclohexyl-2-benzothiazole sulfenamide: off-white granules: Basic accelerator for sulfur-cured diene rubbers, e.g. EPDM, NR, BR, SBR, especially for application in tires and anti-vibration elements: DETU-80: diethyl thiourea: beige granules: Accelerator for the very rapid vulcanization of CR
The general reaction path of accelerated-sulfur vulcanization is thought to be as follows (Coran, 1978; Campbell and Wise, 1964a,b; Hu and Scheele, 1962; Morrison and Porter, 1984; Ghosh et al., 2003): Accelerator reacts with sulfur to give monomeric polysulfides of the structure Ac-S x-Ac where Ac is an organic radical derived from the accelerator (e.g., benzothiazyl-).
