Shandong Baimao Chemical Co., Ltd is a private joint-stock fine chemical enterprises, with a sound management system. Long-term commitment to chemical products research and development, production and marketing. Our products include organic chemical raw materials, textile fuel additives, organic solvents, food additives and feed additives. The products are widely used in pharmaceutical, chemical, building materials, food, cosmetics, plastics, military and other industries. The company has the right to import and export products, in addition to the best-selling domestic market, but also exported to Germany, the United States, Canada, South Korea, India, southeast Asia, the Middle East and other countries and regions. In order to better create a magnificent blueprint for the company, we have established cooperative relations with large multinational enterprises such as Dow, BASF, THSOH CORPORATION, BP, Exxon Mobil and aksu. Domestic: it has formed an alliance with qilu, yanhua, yangzi, jihua and jinzhou petrochemical to establish a complete import and export network, such as acting as agent for the shortage of amines, lipids, alcohols, and various organic and inorganic acids, bases and salts from abroad; From domestic demand for basic chemical raw materials and pharmaceutical intermediates, etc., in the chemical, chemical industry to create a good corporate image, won the business reputation.
Products Description
Polyethylene glycol is a high molecular polymer with the chemical formula HO(CH2CH2O)nH. It is non-irritating, has a slightly bitter taste, has good water solubility, and has good compatibility with many organic components. It has excellent lubricity, moisturizing, dispersion and adhesion. It can be used as antistatic agent and softener in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, papermaking, paints, electroplating, pesticides, metal processing and food. It has a wide range of applications in processing and other industries.
Product advantages
Polyethylene glycol is non-toxic, non-irritating, soluble in water, ethanol and a variety of organic solvents, and insoluble in most aliphatic hydrocarbons and ether. According to different relative molecular masses and different properties. As molecular weight increases, hygroscopic capacity and corresponding lower solubility, as well as preservation point, relative density, flash point and viscosity increase.
