MEG
MEG
MEG (Monoethylene Glycol) is a colorless, odorless, and hygroscopic liquid with the chemical formula C₂H₆O₂, widely used as a key raw material in the chemical and industrial sectors. It is primarily produced through the hydration of ethylene oxide and serves as an essential intermediate in the manufacture of polyethylene terephthalate (PET) resins, polyester fibers, and films. MEG also finds application as an antifreeze and coolant in automotive and industrial systems, as well as a component in hydraulic fluids, heat transfer fluids, and de-icing solutions. Its high boiling point, chemical stability, and miscibility with water make it versatile for both industrial and consumer applications. Due to its role in producing widely used polymers and functional fluids, MEG is considered a critical chemical in the global petrochemical and manufacturing industries, with applications that span textiles, packaging, automotive, and construction sectors.
