[Performance and Application]
Different molecular weights determine different properties and applications. Polyethylene glycol (PEG200-600) with a relatively low molecular weight has solubilizing, dissolving, moisturizing, and heat carrier properties; polyethylene glycol with a relatively high molecular weight is often used as a matrix to adjust viscosity, Melting point, the role of stabilizing the system.
Used as base, solvent, solubilizer, co-solvent, humectant, viscosity and melting point regulator in cosmetics; used as lubricant, wetting agent, softener, antistatic agent in the textile industry; lubricant and wetting agent in the rubber industry , dispersant; used as lubricant and coating agent in the paper industry to increase the gloss and smoothness of paper; used as wetting agent, dispersant, and emulsifier in agriculture; metal processing molding agent; lubricant for metal wire drawing, stamping and forming , cutting fluid, grinding fluid, welding agent; used as dispersant in coatings; used as solubilizer, dispersant, viscosity regulator in ink; used as dispersant and emulsifier in pigments. It is also used in the synthesis of raw materials for ester surfactants.
