(N- tert-butyl-benzothiazole
sulfonamide)
CHARACTERISTICS:
A delayed action accelerator for use in natural
rubber and synthetic rubbers such as SBR, BR, NBR
and EPDM. Lower scorch than CBS and can be
more safely processed. But slightly faster
scorch than OBTS. High modulus and excellent
physical properties, suitable for tire treads and
mechanical goods.
Solubility: Soluble in ethanol, acetone,
benzene, ether, toluene and carbon tetrachloride,
practically insoluble in water
Staining: None
Application: Tires, Industrial goods
