Product Properties: Off-white powder, soluble in benzene, trichloromethane, insoluble in acetone, ethanol, carbon tetrachloride, ethyl acetate, insoluble in gasoline and water. Product Uses:Uses: DDTS has a variety of applications. Firstly, in the petroleum industry, it is used as a desulphurising agent in oil catalytic cracking, effectively removing sulphides from catalytically cracked gasoline. Secondly, in the agricultural field, DDTS is widely used for soil disinfection, which can effectively inhibit the growth of crop pathogens and weeds. In addition, DDTS can be used as vulcanising agent, lubricant and anticorrosion agent for rubber and plastics. MPTD (DDTS) is suitable for natural rubber, styrene butadiene rubber, isoprene rubber, male rubber and nitrile rubber. It is mainly used as a second accelerator in conjunction with accelerators TMTD, TMTM or zinc dithiocarbamate to improve the processing safety of rubber materials. No pollution, no discolouration, easy to be dispersed in the rubber material, suitable for light-coloured and coloured products, short-time rapid vulcanisation moulding products, impregnated products and fabrics hanging glue.
Package: 25kg plastic woven bag, paper-plastic composite bag, 25kg drum.
Storage: It should be stored in a cool, dry and well-ventilated place. Packed products should be kept out of direct sunlight, valid for 2 years.
Company information
The company's main import and export products include
(1)Flavors and Fragrances：Fragrance: some from the natural world of plants and animals or by artificial single separate, synthetic and get the fragrance material called fragrance. Flavour: Flavour is a mixture of a variety of fragrances (sometimes also containing a certain amount of solvent) blended out of a certain aroma, can be used directly for product fragrance, can be widely used in perfumes, cosmetics, shower gels and other daily necessities. Simply put, flavours are made from a mixture of various fragrances.
(2)Organic Raw Materials：It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
