Applications
Uses: MBS has the longest scorch delay of the delayed action thiazole and sulfenamide
accelerators making it ideal for calendered compounds such as steel belt and textile skim
compounds. It is particularly suited for brass coated steel belt adhesion skim compounds. MBS is excellent in compounds that are highly loaded with fine particle size carbon blacks and are difficult to
process. Also used in conveyor power transmission belts, rubber goods with thick cross sections, intricately shaped rubber goods, rubber footwear, injection molded goods, cables and other miscellaneous molded and extruded rubber products.

Polymers: Natural rubber and most synthetic elastomers.

Synergism: MBS cure performance can be boosted with thiuram or guanidine accelerators.

Cure Effect: MBS is a fast delayed action accelerator. MBS provides the longest scorch delay of the thiazole and sulfenamide accelerators. It is very active above 140?C.

Crosslink Type: MBS promotes a balance of mono-, di- and poly-sulfidic crosslinks resulting in vulcanizates with a good balance between heat aging resistance and tear resistance.

Discoloration and Staining: MBS At high concentrations, MBS will give slight discoloration in light colored or white rubber articles on exposure to sunlight. It is non-staining.
