N-tert.-butyl-2-benzothiazol sulfenamide

C₁₁H₁₄N₂S₂

M.W.: 238.37

CAS: 95-31-8

EINECS: 202-409-1

PROPERTIES:

TBBS can lead to long scorching time of rubber compounds, high processing safety and fast cure rate. It can be used alone in low-sulfur vulcanization and can also be combined with dithiocarbamates or thiurams accelerators to improve aging resistance and modulus of generated vulcanizate. And this combination can significantly lower the vulcanization rate. Thioureas accelerators have obvious secondary acceleration to TBBS, especially in low-sulfur rubber compounds. TBBS can delay scorching in rubber compounds contained thiols and thiurams accelerators.

DOSAGE:

For NR: 0.5-1.0phr with 2.5-3.5phr sulfur; for SBR: 1-1.4phr with 0.2phr thiurams accelerators and 1.5-2.5phr sulfur.

APPLICATIONS:

Tyre treads, hoses, conveyor belting, shoes and other industrial products.
