Other Name: P-Toluene Sulfinic Acid Zinc Salt; Zinc P-Toluene Sulfonate Hydrate; Zinc P-Toluenesulphinate; P-Toluenesulfonic Acid Zinc Salt Hydrate; TM; Blowing Agent Activator ZTS CAS No :123334-05-4 Molecular Formula: (CH3C6H4SO2)2Zn  Product Usage: It's a new type of alkyl aromatics sulfonic acid zinc compound. As a stabilizer & lubricants & activator,it's used in synthetic rubber of PE, PVC, polypropylene nylon, ABS natural rubber, butylbenzene rubber,etc. Compared with any other stearic acid salt, TM has the superior light stability, heat stability and good transparency. It's easy to scattered in plastic and rubber,and can greatly reduce the temperature of decomposition when it's used with AC foaming agent together.  Check-Point Unit Specifications Appearance -- White Powder Purity  min 98 Water  max 0.5 Melting Point °C max 255 Heavy Metal ppm max 10 Iron ppm max 5 Ash  max 24
Commodity: Dicalcium phosphate Feed Grade Use DCP is the feed preparation of raw materials, Animal right to supplement calcium needs. Coarse its products more applicable to the preparation hens, ducks feed, concentrate feed and premix. Product Nature Molecular Formula:CaHPO4·2H2O,Molecular weight:172.09,After drying with loose white powdery crystals or granules. Neutral products, the melting acid, water-soluble, hygroscopicity small, heated to 90 around gradually lose water of crystallization. Product Features The purity of the product, calcium and phosphorus ratio appropriate to ensure a higher degree of its biological effects. Phosphorus content greater than 18% of the products, due to a small amount of MCP, and its biological effects better. This unique high-tech companies use technology to make our products crystallization, high purity and its harmful impurities significantly below standards:HG26362000 Drying process advanced products, products with low free water under the premise that the product does not lose crystallization of water, avoid the product in the drying process for the loss of water caused by crystallization of biological effects of the reduction. Coarse particle DCP in the animals stay in the stomach longer and more conducive to the absorption of calcium phosphate, the product of Micro-particle DCP granulation from mechanical, without any chemical binder.
