The application of PEG

The application of PEG is to provide lubricity for many products, such as: metal, ceramic tile, porcelain forming lubricant, spinning and spinning.Weaving fibers, lubricants for tires and medical surgical sutures, release agents made of latex foam, etc. Among them, concrete is the most used building material in the world. Among the concrete admixtures, the most used and most widely used is water reducing agent, which accounts for 70% to 80% of the total amount of admixture. Polycarboxylate superplasticizer is another new type of superplasticizer after naphthalene based superplasticizer and melamine based water reducer. At present, the main monomer raw materials for synthesizing polycarboxylic acid series high performance water reducing agents are methoxy PEG (MPEG) and allyl PEG (XPEG). Because PEG is non-toxic, chemically stable, and does not undergo any chemical reaction with the drug, it is widely used in the pharmaceutical industry. PEGs of different relative molecular masses have the functions of thickening, emulsifying and solidifying. Because PEG has excellent water solubility, non-volatile, non-greasy, good skin affinity, light color and low toxicity, it is a very good neutral base in cosmetic formulations. Low molecular weight PEG is added to cosmetics. It has the functions of thickening, emulsifying and moisturizing the skin, softening the hair and increasing the luster. It has no side effects on the skin and has the effect of skin care. PEG and PEG esters are mainly used for washing in the textile industry.Agent, softener, lubricant, antistatic agent, dispersant, dye carrier,Air conditioner and finishing agent.
