(min)c142.0 3loss on drying (max)%0.40 4ash (max)%0.30 5residue on 150m sieve (max)%0.10 Properties:no odor and poison. Irritating to the skin and the respiratory tract. Specific gravity: 1.38--1.44. Soluble in chloroform, acetone, benzene; hardly soluble in carbon tetrachloride, ethyl alcohol & insoluble in water or gasoline. Application:can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and ev cure systems. Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for epdm. May be used as a retarder in the vulcanisation of polychloroprene rubber with etu. Storage:keep container tightly closed in a cool, well-ventilated place. The recommended max. Storage life is 2 years when stored under normal conditions. Packaging: 25kg bag.
TMTD is used as a single promoter in most sulfur vulcanized elastomers.Can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and EV cure systems good color retention is obtained in non-black vulcanisation. Widely used in natural rubber and synthetic rubber, mainly used in industrial products such as tyres, tyre tube, rubber overshoes, cables. Used as bactericide and pesticide in agriculture, also as lubricating additive.
