Application:

1) 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-TB7 are used in the innerliner, chafer,bead apex, sidewalls, and tread. Industrial applications include noise damping blocks, motor mounts, dock fenders, elastic threads, automobile engine hoses, gaskets, belts, and other industrial rubber products that require good heat resistance.The VA-TB7 also aid in rubber processing. VA-TB7 polychloroprene vulcanizates have improved flex life.

2) bleaching agent in the disproportionation of rosin or rosin esters.

Characteristics:

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

2) Synergism: Can be used with most typical rubber accelerators and sulfur. When used as a partial replacement for sulfur, VA-TB7 tends to improve dispersion of other additives in the rubber.

3) Crosslink Type: VA-TB7 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

4) Non-nitrosamine: VA-TB7 does not produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams.
