  • MBTS (powder/granule) ex Sunsine, China
    A versatile semi-ultra accelerator with good processing safety. It may be used alone or in conjunction with other accelerators. During the processing and vulcanization of CR compounds it has a retarding effect.

MBTS is Semi ultra Thiazole Accelerator. It is a fast curing accelerator giving vulcanisates with ultimate properties closely similar to those of MBT. The most noticable difference is the much greater scorch resistance of MBTS.

Like MBT, MBTS gives extremely good ageing properties; it is practically non-staining and similarly needs the addition of stearic acid to function at its maximum efficiency. In combination with guanidines, thiurams and
dithiocarbamates, it gives rapid curing but safe mixtures, In Neoprene, it serves as an antiscorch agent. Typical
usage in rubber varies from 1.0 – 1.5 phr.
