MEG (Monoethylene Glycol)
Description
Monoethylene Glycol (MEG) is a colorless, virtually odorless and slightly viscous liquid. It is miscible with water, alcohols, aldehydes, and many organic compounds. MEG will not dissolve rubber, cellulose acetate or heavy vegetable and petroleum oils. MEG has a low volatility and it is 50% more hygroscopic than glycerol at room temperature.
Applications
MEG is mainly used in the production of polyester, polyethylene terephthalate (PET), and antifreeze solutions. It is an important dehydrating agent, good humectant, and an industrial solvent.
