Monoethylene glycol (MEG) is a clear, odorless liquid widely used as a key chemical intermediate in many industries. It is essential in the production of polyester fibers, resins, and PET packaging materials. MEG also plays a critical role as an antifreeze and coolant, lowering the freezing point and raising the boiling point in heat-transfer systems and de-icing solutions. Additionally, it is used in adhesives, inks, leather processing, and natural gas dehydration, making it a versatile and valuable industrial chemical.
