What is MBTs (benzothiazyl disulfide)?

MBTS (Benzothiazyl Disulfide) is a non-staining, primary thiazole accelerator for use in natural and synthetic rubbers. It is very active at temperatures above 280°F. Activation requires the addition of zinc oxide, a fatty acid and sulfur for cure development.

How is MBTs used in a polychloroprene cure system?

Activation requires the addition of zinc oxide, a fatty acid and sulfur for cure development. Secondary accelerators used in conjunction with MBTS such as aldehyde amines, dithiocarbamates, guanidines, and thiurams will increase cure rates. MBTS is also used as a retarder in polychloroprene cure systems, as well as a retarder for peroxide cures.

What is the difference between MBTs and sulfenamides?

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. Packed in Kraft paper bags of 25kgs net each with P.E. liner inside, or jumbo bags. 12Mt per 20’GP, 24Mt per 40’GP, palletized.

What is MBTs used for?

MBTS is also used as a retarder in polychloroprene cure systems, as well as a retarder for peroxide cures. Blends of MBTS and BBTS are often employed in tire vulcanization cure systems. MBTS is a safe processing accelerator, but increased scorch resistance can be obtained with the addition of Retarder PX, Retarder AK, or Retarder SAFE.

What temperature is MBTs active?

It is very active at temperatures above 280°F. Activation requires the addition of zinc oxide, a fatty acid and sulfur for cure development. Secondary accelerators used in conjunction with MBTS such as aldehyde amines, dithiocarbamates, guanidines, and thiurams will increase cure rates.

Is accelerator MBTs available in a polymer bound dispersion?

Accelerator MBTS is also available in a polymer bound dispersion. Several polymer carriers are available. These polymeric masterbatches contain 70-80% Accelerator MBTS and are very soft for ease of incorporation. Akrochem polymer bound dispersions eliminate irritating dust, as well as other potential hazards in handling powders in the plant.
