Fiber-grade Monoethylene Glycol (MEG, CAS 107-21-1), min. 99.5%, supplied wholesale by Zyntex. Raw material for PET and polyester, base for antifreeze and heat transfer fluids, and gas hydrate inhibitor. CoA and SDS.
Monoethylene glycol (HOCH2CH2OH) is a clear, colorless, viscous liquid with a slightly sweet taste. It also boils at about 197°C, mixes completely with water and lowers the freezing point of water strongly.
In addition, polyester producers react MEG with Terephthalic Acid to make PET for bottles, fibers and films; this is by far its largest use. Similarly, coolant producers use it as the base of engine antifreeze and industrial heat transfer fluids, while gas producers inject it to prevent hydrate formation in natural gas pipelines. It also serves as a raw material for resins and as a solvent.
MEG is toxic if swallowed, so antifreeze products often contain bittering agents. Related glycols in our range also include Diethylene Glycol DEG and Polyethylene Glycol (PEG).
Typical uses include, for example:
🍶 PET and Polyester
Raw material for bottles, fibers as well as films.
🚗 Antifreeze
Base for engine coolants.
🌡️ Heat Transfer Fluids
Base for industrial cooling systems.
⛽ Gas Dehydration
Hydrate inhibitor in natural gas pipelines.

What is the main use of MEG?
Mainly as a raw material for PET and polyester, together with terephthalic acid, as well as in antifreeze and heat transfer fluids.
What is the difference between MEG and diethylene glycol?
MEG is the simplest glycol used for PET and antifreeze, whereas diethylene glycol is a by-product used mainly in resins and as a solvent.
