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.
Storage and Handling
Stable indefinitely under normal storage conditions. No special handling precautions are necessary. Normal
precautions to avoid contact with skin and eyes should be followed. For eyes, flush with plenty of water and
seek medical advice.
