Applications  DTDC is a not discoloring sulfur donor for natural and synthetic rubber and latex, especially

for low sulfur vulcanization,salt bath vulcanization,injection moulding and for vulcanization of

thick-walled provides mono-and di-sulfur bridges which are more stable than those

formed by elemental sulfur.In contrast to other sulfur donors DTDC does not form nitrosamines

which can cause cancer and is thus a very safe rubber additive. DTDC could replace DTDM

due to its property.


Storage    The product should be stored in the dry and cooling place with good ventilation,avoiding

exposure of the packaged product to direct sunlight.


Packing    In 25kg paper bags with plastic inner.
