Properties and Usage:

Uses: Sulfur donor for natural and synthetic rubbers. VA-TB7 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics. VA-TB7 can be used as either complete or partial replacements for sulfur and thiuram and DTDM sulfur donors in EV and semi-EV type cure systems. In tires VA serials are used in the innerliner, chafer, bead apex, sidewalls, and tread. 

Polymers: Natural rubber and synthetic elastomers. Especially good in curing rubber that contains chlorine such as chlorobutyl and polychloroprene.

Synergism: Can be used with most typical rubber accelerators and sulfur. When used as a partial replacement for sulfur, VA tends to improve dispersion of other additives in the rubber.

Crosslink Type: VA promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

Non-nitrosamine: VA does not produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams.
