Monoethylene Glycol at a Glance
Monoethylene Glycol (MEG) is a basic glycol with the formula C2H6O2 that is widely used in the production of polyester fibers, PET bottles, automotive antifreeze, natural gas systems, and the chemical industry, and is one of the most widely used petrochemicals in the world.
What is monoethylene glycol?
Monoethylene glycol is produced by the reaction of ethylene oxide with water under controlled conditions. It is the simplest member of the ethylene glycol family and, due to its small molecular structure, has very high moisture absorption properties, a suitable boiling point, and excellent solubility in water.
MEG is a strategic material in the downstream petrochemical industries, with more than 60% of its global consumption used in the production of polyesters and synthetic fibers. For product details, visit the Monoethylene Glycol product page.
