MPEG in Production of Polycarboxylate Superplasticizer
Methoxy Polyethylene Glycol is used in many applications from industrial manufacturing to medicine. Its water solubility, wettability and physiological characteristics make it very attractive for the cosmetic and pharmaceutical industry. It is also used in food products and as processing aid in many industrial applications. Common uses are as surfactant, dispersing agent, solvent, excipient, ointment. Its functionality depends of its molecular weight. MPEG with low molecular weight average (less than 2000) are used as wetting agent, viscosity modifier. Higher molecular weight MPEG (more than 2000) are used to produce MPEG acrylic esters, which are used as efficient reducing agent in the materials of constructions needed for high strength structures.
