Monoethylene Glycol (MEG) Manufacturer & Bulk Supplier | Price & Technical Specs

What are the main industrial uses of Monoethylene Glycol (MEG)?

Monoethylene Glycol (MEG) is primarily used in two major areas: as a key ingredient in the production of polyester fibers and PET (polyethylene terephthalate) plastics, and as an essential component in antifreeze and coolants due to its excellent heat transfer properties.

What is the Monoethylene Glycol CAS No. and chemical formula?

The Monoethylene Glycol CAS No. is 107-21-1. Its chemical formula is C2H6O2. It is the simplest member of the glycol family.

What is the typical MEG purity required for polyester grade applications?

For demanding applications like polyester fiber and PET resin manufacturing, a high purity of 99.8% or higher is typically required to ensure optimal polymerization and final product quality.

What is the boiling point and freezing point of pure Monoethylene Glycol?

Pure Monoethylene Glycol has a high boiling point of 197.3C. Its freezing point is -12.9 C, which is why it is effective in creating low-freezing antifreeze mixtures.

Is MEG the same as antifreeze?

No, pure MEG is a raw material. Antifreeze is typically a mixture of 40% to 60% Monoethylene Glycol and water, along with corrosion inhibitors and dyes. This mixture achieves a much lower freezing point than pure MEG or pure water.

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

MEG (Monoethylene Glycol), DEG (Diethylene Glycol), and TEG (Triethylene Glycol) are all ethylene glycols. They differ in the number of ethylene oxide units. MEG is the simplest and is preferred for polyester production.

How is MEG generally supplied and handled in bulk?

As a major Monoethylene Glycol manufacturer and supplier, we provide MEG in bulk via ISO tanks, flexi-bags, or in 230 kg HDPE drums. Handling requires careful adherence to the MEG SDS (Safety Data Sheet), including proper ventilation and storage.

Why does the Monoethylene Glycol price fluctuate?

The Monoethylene Glycol price is strongly influenced by the global price of its petrochemical feedstock (Ethylene), global supply-demand dynamics for polyester (PET), and seasonal demand for antifreeze products.

Do you provide technical grade and polyester grade MEG?

Yes, we supply both Technical Grade (suitable for general industrial use, coolants, and solvents) and highly specialized Polyester Grade MEG, which meets stringent purity requirements for polymer production.
