Full Description

Ethylene glycol (CAS 107-21-1), also called monoethylene glycol (MEG), is a low-viscosity diol and one of the highest-volume glycols in commerce. Its largest use is as antifreeze and heat-transfer/coolant fluid; it is also a primary feedstock for polyester fibers and polyethylene terephthalate (PET) resin. Additional roles include humectant, deicing, and solvent applications.

Frequently Asked Questions

What is ethylene glycol used for?

Ethylene glycol (CAS 107-21-1, also called monoethylene glycol or MEG) is used largely as antifreeze and heat-transfer/coolant fluid and as a primary feedstock for polyester fibers and PET resin. Additional roles include humectant, aircraft and surface deicing fluids, and co-solvent in coatings and process fluids.

What is another name for ethylene glycol?

Ethylene glycol is also called monoethylene glycol (MEG) and ethanediol. It is a low-viscosity diol (C2H6O2) and one of the highest-volume glycols in commerce.

What is the difference between MEG, DEG, and TEG?

MEG is monoethylene glycol (this product), DEG is diethylene glycol, and TEG is triethylene glycol — successively larger glycol oligomers with different boiling points, viscosities, and applications. MEG is the highest-volume of the three and the primary PET and antifreeze feedstock. Specify the glycol your application requires.

How is ethylene glycol packaged and shipped?

Ethylene glycol is not assigned a UN number for general transport as a hazardous material; it ships in bulk — drums, totes/IBCs, and bulk volumes — with CoA and SDS provided. Confirm classification for your destination and refer to the SDS for handling details.

What is the cost of bulk ethylene glycol (MEG)?

Bulk MEG pricing depends on grade (e.g., fiber/antifreeze), packaging, and volume and tracks feedstock markets. Submit a bulk RFQ with your specification and quantity for a current quote; we do not list spot prices.
