Sovchem® MBT Granule
Applications
Uses: Fast curing primary accelerator suitable for use in most polymers. Best results are obtained with a combination of MBT as the primary accelerator and thiuram, dithiocarbamate or guanidine accelerators as boosters. MBT acts as a retarder in CR based compounds. MBT acts as a mild peptizer for NR and CR rubbers. Applications include motor cycle/scooter tires, butyl tubes, belts, retreads, footwear, hot air cured products, hoses, cables and miscellaneous molded
and extruded rubber products.
Polymers: Natural rubber and most synthetic elastomers.
Synergism: MBT cure performance can be boosted with thiuram, dithiocarbamate or guanidine accelerators.
Cure Effect: Promotes a flat fast cure rate. MBT is a moderately low activation temperature -very active above 115°C.
Crosslink Type: MBT promotes a balance of mono-, di- and poly-sulfidic crosslinks resulting in vulcanizates with a good balance between heat aging resistance and tear resistance.
Color: MBT itself does not discolor white compounds; however, a slight yellowing effect is observed when white colored products are exposed to sunlight.
