Accelerator T is also the super accelerator of natural rubber, diene synthetic rubber, Ⅱ, R and EPDM, with the highest utilization rate of all.
The vulcanization promoting force of accelerator T is very strong, but, without the presence of zinc oxide, it is not vulcanized at all.
Tetramethylthiuram disulfide (TMTD) is used for the manufacture of cables, wires, tires and other rubber products.
Tetramethylthiuram disulfide (TMTD) is used as the super accelerator of natural rubber, synthetic rubber and latex.
Tetramethylthiuram disulfide (TMTD) is used as the late effect promoter of natural rubber, butadiene rubber, styrene-butadiene rubber and polyisoprene rubber.
Tetramethylthiuram disulfide (TMTD) is used for the pest control of rice, wheat, tobacco, sugar beet, grapes and other crops, as well as for the seed dressing and soil treatment.
Tetramethylthiuram disulfide (TMTD) is suitable for the manufacture of natural rubber, synthetic rubber and latex, and can also be used as curing agent.
Tetramethylthiuram disulfide (TMTD) is the second accelerator of thiazole accelerators, which can be used with other accelerators as the continuous vulcanization accelerator.
Tetramethylthiuram disulfide (TMTD) can be used as the super-vulcanization accelerator, and aften used with thiazole accelerator.
Safety Profile Of Tetramethylthiuram disulfide (TMTD):
Poison by ingestion and intraperitoneal routes.
Mutation data reported, Affects human pulmonary system.
Tetramethylthiuram disulfide (TMTD) a rmld allergen and irritant.
Acute poisoning in experimental animals produced liver, hdney, and brain damage.
Questionable carcinogen with experimental tumorigenic and teratogenic data.
Other experimental reproductive effects.
Toxic effects of thiram have been described in humans and animal model systems ranging from liver injury, testicular toxicity, ophthalmological changes, and development of micronuclei in bone marrow.
However, the mechanisms of these effects are not characterized and inconsistent across various studies.
Tetramethylthiuram disulfide (TMTD) appears to result from its potential to disrupt cellular defense mechanisms against oxidative stress.
In cultured human skin fibroblast, Tetramethylthiuram disulfide (TMTD) results in an increase in oxidative markers such as lipid peroxidation and oxidation of reduced glutathione and decrease in other endogenous antioxidant.
Health Hazard Of Tetramethylthiuram disulfide (TMTD):
Inhalation of dust may cause respiratory irritation.
Liquid irritates eyes and skin and may cause allergic eczema in sensitive individuals.
Ingestion causes nausea, vomiting, and diarrhea, all of which may be persistent; paralysis may develop.
Fire Hazard Of Tetramethylthiuram disulfide (TMTD):
Special Hazards of Combustion Products: Toxic and irritating oxides of sulfur are formed.
Carbon disulfide may be formed from unburned material.
