What is zinc stearate? Zinc stearate is non-toxic, pollution-free, has no dangerous characteristics, adsorption, and good adhesion to the skin. Insoluble in water, ethanol, ether, hot ethanol, turpentine, benzene and other organic solvents. Strong acid decomposition into stearic acid and its corresponding salts. Zinc stearate is combustible in dry conditions, the ignition point is about 900℃, and the mixture of dust and air has an explosion risk in the open fire.
Main uses of zinc stearate Zinc stearate can be used as a heat stabilizer; lubricant; grease; accelerator, etc. For example, it generally can be used as a PVC resin thermal stabilizer; For general industrial transparent products; Use it with a calcium soap. It Can be used in non-toxic products, Used in soft products, But in recent years has started using hard, transparent products such as mineral water bottles, Upper water pipes and other products; Good lubricity of zinc stearate, Can improve the phenomenon of scaling and precipitation, Can also serve as a lubricant, mould discharging agent, And paint, Additives of the coatings; Can also be used as styrene resin, phenolic resin, amine-based resin lubricant and release agent; It also has an active sulphide agent in rubber, Function of the softener; Zinc stearate has a slippery enhancement in water-based coatings, Increase the role of burnability; It is also a promoter that cannot be missing in foaming products. The production method of zinc stearate: There are two ways of production of zinc stearate: the water method and the melting method. Zinc stearate produced by water is acidic and alkaline by melting. Water method, also known as the wet method, under the condition of the water as a medium, the catalyst is added to control a certain temperature and pressure. Then the metal hydroxide is added, and the metal ions are replaced to the catalyst through the catalyst and then replaced by the stearic acid through the catalyst itself to generate metal salt. The catalyst is through post-sequential treatment and recycling. Stearate after centrifugation, drying and grinding to obtain the number of 200-600 products that meet the industry standards. Water production is usually slightly excessive in stearic acid, so the finished product is acidic after the reaction. The melting method, also known as the dry method, refers to directly adding metal oxide (zinc oxide) into the molten stearic acid to control a certain temperature, pressure and stirring speed and obtain stearate through reaction. The products produced by the dry method can be completely reacted due to the existence of the catalyst and the general reaction results. The metal oxide is slightly excessive, so the product is alkaline when testing. Price of zinc stearate The different price of zinc stearate purity is also different. The market price of zinc stearate is in the process of dynamic change. The price of zinc stearate can be found on our company's official website. If you need it, you can ask us at any time.
