Buying Guide: Ethylene Glycol

By Coco Ho

Ethylene glycol (MEG) is a clear, colorless, and odorless liquid widely used in the chemical, textile, and automotive industries.

Its chemical formula is C₂H₆O₂, and it is produced by the hydration of ethylene oxide. This compound plays a major role as a raw material in polyester production and as an antifreeze and coolant ingredient.

What Is Ethylene Glycol Used For?

Ethylene glycol is mainly used in four major industries:

Polyester Fiber and PET Resin:
Over half of global MEG production goes into polyester fiber and PET bottle manufacturing. It reacts with purified terephthalic acid (PTA) to produce polyethylene terephthalate (PET) used in textiles and packaging.
Antifreeze and Coolant:
It prevents water from freezing in engines during cold weather and from boiling during high temperatures, making it ideal for automotive coolants and de-icing fluids.
Industrial Solvent and Resin Production:
Used in resins, paints, and coatings, ethylene glycol provides excellent solvency and moisture control.
Heat Transfer and Dehumidifying Systems:
Due to its stable thermal properties, MEG is used in HVAC and solar systems as a heat transfer fluid.

Packaging and Storage

Ethylene glycol is typically packaged in ISO tanks, 200L steel drums, or 1000L IBC totes. Store it in a cool, dry, and well-ventilated place. Keep containers tightly sealed and away from oxidizing agents.

Ethylene Glycol Price

The global ethylene glycol price fluctuates with crude oil and polyester demand.

China Domestic: ¥3,800–¥4,200 per ton
Export FOB China: USD $500–$650 per ton
Bulk buyers, distributors, and dealers often secure lower prices through long-term contracts with China manufacturers and suppliers.

Leading Chinese Manufacturers and Suppliers

China has many reliable ethylene glycol manufacturers, factories, and exporters, including:

Sinopec Chemical
PetroChina
Wanhua Chemical
Satellite Chemical
Sanjiang Fine Chemical

They provide high-purity MEG suitable for polyester-grade and industrial-grade applications. Buyers can source directly from these Chinese factories or through authorized distributors and dealers for smaller orders.

How to Buy

Choose the required purity and packaging.
Request COA and MSDS from suppliers.
Compare quotations from multiple China exporters.
Confirm Incoterms (FOB, CIF, or DDP).
Order samples for quality testing before bulk purchase.

Summary

Ethylene glycol is a vital raw material in textiles, PET packaging, and automotive fluids. Sourcing from reliable Chinese manufacturers, suppliers, and exporters ensures consistent quality, competitive cost, and stable long-term cooperation. Whether you are a buyer, distributor, or dealer, understanding the market, verifying purity, and tracking current ethylene glycol prices are key to successful purchasing.
