Accelerators and Antioxidants for rubber compounds Caldic
The vulcanization of rubber, both natural and synthetic, requires the use of accelerators, sulphur donors and activators for several reasons: speeding up the vulcanization process and making it more controlled, improving the performance of the finished article and replacing, partly or totally, sulphur in "Semi EV" or "EV" systems.
MBTSor benzothiazole disulfide was originally developed for safe processing rubber compounds cured at or above 142°C (287°F). MBTS continues to be used widely in compounds of all types for many major commercial applications.

Accelerator (i) is marketed by a UK rubber chemicals supplier. These accelerators (ii) to (v) are marketed by rubber chemical suppliers generally. Tetramethylthiuram disulfide, a well-established accelerator produced by several manufacturers, would only be used in conjunction with other accelerators such as (i) to (iv) above for the present

Aug 01, 1999· MBTS and sulfur are sometimes used in BIMS compounds. The MBTS decomposes to MBT by the action of zinc oxide and sulfur. Since MBT is a mono-functional nucleophile, it will react with the benzyl bromide sites forming nonreactive mercaptobenzothiazyl benzyl sulfides. MBT is thus a scavenger of reactive sites (figure 15).

Accelerator VS is typically used in EPDM and NR compounds. This accelerator tends to be scorchy, but certainly is a viable alternative. Accelerator ZIX is a very fast accelerator and chemically known as zinc iso-propylxanthate. Due to its very scorchy nature, this accelerator has a very limited but important use in the rubber formulations.

Vulcanization & Accelerators
widely used accelerators in the rubber industry for the production of wide variety of goods such as cycle tyres and tubes, footwear, beltings, hoses and other moulded and extruded goods. Thiazoles are activated by Zinc oxide / Stearic acid combination and produce flat cure with vulcanizates having
Accelerators are commonly used in conjunction with sulphur, zinc oxide, and stearic acid in vulcanization. Primary accelerators are used in the manufacture of tyres, while secondary accelerators are used to improve the vulcanization speed and healing state. Flame retardants are commonly used to avoid incidents and heat from burning rubber.
