CARBOWAX™ PEGs for Industrial Applications

Choose from CARBOWAX™ PEGs in a variety of molecular weights, viscosities and in several physical forms. Each product grade is designated numerically by its average molecular weight. For example, CARBOWAX™ PEG 600 consists of a distribution of polymers of varying molecular weights with an average of 600. Molecular weight has an effect on the physical properties of each product grade. Increased molecular weight results in decreased solubility in water and solvents, decreased hygroscopicity and vapor pressure, and increased melting/freezing range and viscosity.
