***Typical Properties

Light yellow powder, The relative density is 1.45~1.50. In room temperature, it slightly dissolved in benzene, toluene, carbontetrachloride,trichlorobenzenes, acetone, ethanol, ethyl ether,and not dissolve in water, ethyl acetate, petrol and lye.

***Recommended Applications

It gives moderate processing safety and moderately fast cures with flat plateau. The vulcanizate characteristics are similar to thoseobtained with MBT.In fact, MBTS can ofen be used when MBT is too scorchy.

Compounds cased on 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.

***Handling and Storage recommendations

Store MBTS in a cool, dry, well-ventilated area, avoiding exposure of the packaged product to direct sunlight. Usually the shelf time is 24months while the recommend use of date is in 12 months.
