Methylene glycol (MEG) is a widely used industrial solvent and chemical intermediate known for its hygroscopic properties and compatibility with water and alcohols. It is primarily used in the production of polyethylene terephthalate for plastic bottles and packaging, and as a coolant and antifreeze in automotive and HVAC systems. Additionally, it plays a role in the textile and paper industries for moisture control, in oil and gas pipelines to prevent hydrate formation, and in the formulation of inks, adhesives, and paints. Its versatility and chemical stability make it essential across a broad range of manufacturing and processing applications.
