Polyethylene glycol(PEG)
Main application：
This series of products are usually soluble in water and a variety of organic solvents, insoluble in aliphatic hydrocarbons and phenylglycol, and will not be hydrolyzed and deteriorated. They are low-toxic substances, non-irritating, and non-ionic polymers. They have excellent lubricity, moisture retention and dispersibility, and are used in adhesives, antistatic agents and softeners. It can be used as a medium for organic synthesis and a heat carrier with higher temperature requirements; in the daily chemical industry, it can be used as a humectant and an inorganic salt solubilizer. It can also be used as a base, lubricant or softener for medicines and cosmetics to adjust the melting point and viscosity. In the rubber industry, it can be used as a lubricant, dispersant, promoting and regulating vulcanization. In the chemical fiber industry, it can be used as a polymerizable monomer for dyeable polyester, which can improve the dyeability of polyester and the comfort of fabrics. In addition, it is widely used in plastics, papermaking paint, electroplating, pesticides, metal processing and food processing industries.
