Eastman TMTD (Tetramethylthiuram Disulfide) C
TMTD is widely used in rubber processing as an ultra accelerator for low-temperature cures, either alone or as an activator for other accelerators, chiefly the thiazoles. With sulphur in conjunction with zinc oxide and fatty acid as activators (0.1 1% TMTD on the weight of the gum), In conjunction with accelerators such as
Oct 10, 2008· In response to the growing interest in Allergic Contact Dermatitis, several glove manufacturers have introduced accelerator-free products. Chemical accelerators such as thiazoles, thiurams and dithiocarbamates are known contact sensitizers. They are used widely in the manufacture of natural rubber latex, nitrile and neoprene gloves.

China DCBS POWDER Manufacturer, Suppliers, Factory
Common industrial sulfur additives TMTD, TETD, etc. can produce carcinogenic N-nitrosodimethylamine when vulcanized. At present, platinum vulcanizing agent (low vulcanization temperature and fast vulcanization speed) is widely used as a vulcanizing agent for silicone rubber in some special products.
Accelerator 553SN is a solution of metal complexes, partly based on a cobalt salt in an organic solvent. Accelerator 553SN gives in comparison with the commonly used cobalt accelerator a much faster cure with comparable gel time. Accelerator 553SN is therefore very suitable where a faster demoulding time of the end product is required.
