Product type
Monoethylene Glycol (MEG) is a colorless, odorless, and hygroscopic liquid that is primarily used as an intermediate in the production of polyester fibers and resins. It is produced from ethylene oxide through a process of hydrolysis. MEG is a key raw material in the manufacture of polyethylene terephthalate (PET), which is widely used in textiles, plastics, and packaging applications. Additionally, MEG serves as an antifreeze agent and coolant in automotive and industrial applications.

When selecting Monoethylene Glycol, buyers should consider the required purity level, as higher purity grades are essential for specific applications like textiles and food packaging. It is also important to specify the desired quantity and any necessary certifications, especially for applications in regulated industries. Understanding the intended use can help in determining the appropriate specifications and any additional additives that may be needed.
