Gray white powder/granule.The relative density is 1.45~1.50. In room temperature, it slightly dissolved in benzene, toluene, carbon tetrachloride,trichlorobenzenes, 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 vulcanized characteristics are similar to those obtained with MBT. In fact, MBTS can be usually used when MBT is too scorch.
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.
