Poduct Properties: White powder (granule). Relative density is 1.66, soluble in dilute alkali, carbon disulfide, benzene, acetone and dichloromethane, slightly soluble in chloroform, insoluble in ethanol, carbon tetrachloride, ethyl acetate.
Product Uses: Super accelerator for natural rubber and synthetic rubber and general accelerator for latex. It is especially suitable for butyl rubber and nitrile rubber with good aging resistance which have requirements for compression deformation, and it is also suitable for EPDM rubber. The curing temperature is 100℃, the activity is a little stronger than WllLING TMTD, but the activity is stronger at low temperature, the tendency of scorching is big, and it is easy to cause early vulcanisation when mixing. It has activating effect on thiazole sub-sulfonamide accelerators and can be used as the second accelerator. It can be used as the second accelerator. When it is used with Willing DM, the anti-scorching property will increase with the increase of DM dosage. Since it is odourless, non-polluting and non-discolouring, it is suitable for adhesive tape, food and medical Rubber Products. In the United States, ZDMC has been approved by the FDA. It is effective in EPDM rubber, butyl rubber and other products.
Zinc Diethyldithiocarbamate (Zn(S2CNEt2)2, ZDTC) is used as an organocatalyst for the synthesis of high molecular weight polyurethanes from PEG and PPG-diol macromolecules for biomedical applications. Compared to other zinc catalysts, ZDTC shows outstanding activity in the preparation of polyurethanes due to its tolerance to different organic solvents.
It can also be used as:
Catalyst for polymerisation of olefin oxides.
As a precursor for the preparation of zinc sulfide semiconductor nanowires, the nanowires can be used as structural units for photonic devices.
Packing: 25kg plastic woven bag, paper-plastic composite bag, kraft paper bag.
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.
Description: This product can be made into ultra-fine powder according to customers' requirements.
Company information
The company's main import and export products include
(1)Water Treatment:Physical methods also include precipitation, is to let the impurities of smaller specific gravity float on the surface of the water to fish out, or the impurities of larger specific gravity precipitation in the lower, and then obtain. Chemical method is to use a variety of chemicals in the water impurities into less harmful substances, or impurities concentrated, the longest history of chemical treatment methods should be considered to be added to the water with alum, the collection of impurities in the water, the volume becomes larger, it can be used for filtration, the removal of impurities.
(2)Intermediates：Intermediates are semi-finished products, which are products in the middle of the production of certain products, for example, to produce a product, which can be produced from intermediates to save costs.Intermediates are available from cyclic compounds such as benzene, naphthalene, anthracene, etc. by sulfonation, alkali fusion, nitration, reduction and other reactions.Our Intermediates products include pharmaceutical intermediates, pesticide intermediates and dye intermediates.
