Oc 144.0 Heating loss 0.40 Ash 0.40 Residues on sieve(150m), % 0.10 Properties:grayish-white powder. No taste, no poison. Densiy is 1.08-1.19. Soluble in acetone, ethyl acetate, benzene, alcohol, slightly soluble in ccl4; insoluble in water and gasoline. Application:used as a secondary accelerator with thiazoles and sulphenamides in nr and sbr compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. Dpg can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process Packing: 25kg in kraft paper bag with pe bag inside, or 25kg in plastic woven bag with pe bag inside, or as customers request. Storage:keep in a cool, well-ventilated place. The shelf life is 2 years. Notes: the products could be oil coated powder, as per customers request.

Rubber accelerator tmtd Specification: Chemical name:tetramethyl thiuram disulfide Cas no: 137-26-8 Specification: no.Itemunitspecification 1appearance-white powder 2initial m.P. (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.
