Density at 20℃ (g/cm3)
Rubber Accelerator MBTS is Gray powder, The relative density is 1.45~1.50. In room temperature, it slightly dissolved in benzene, toluene, carbon tetrachloride, trichloro benzenes, acetone, ethanol, ethyl ether,and not dissolve in water, ethyl acetate, petrol and lye.
It gives moderate processing safety and moderately fast cures with flat plateau.
The vulcanizate characteristics are similar to those obtained with Rubber Accelerator MBTS.In fact, It can often be used when MBT is too scorchy.
Compounds cased on Rubber Accelerator MBTS have slightly better aging and reversion resistance than corresponding ones based on sulfenamides.
It can be boosted by use of secondary accelerators to achieve a faster cure and higher modulus.
Store Rubber Accelerator MBTS in a cool, dry, well-ventilated area, avoiding exposure of the packaged product to direct sunlight.
Usually the shelf time is 24 months while the recommend use of date is in 12 months.
