Éthylène glycol - Liquide de refroidissement de qualité industrielle

Ethylene Glycol (C₂H₆O₂) is a clear, odorless, sweet-tasting liquid primarily used in the production of antifreeze formulations et polyester fibers. As a hygroscopic alcohol with a low freezing point and high boiling point, it is ideal for use in cooling systems, heat exchangers, et hydraulic fluids.

It plays a vital role in various chemical processes and polymer manufacturing. Our Ethylene Glycol is industrial-grade and produced using state-of-the-art catalytic oxidation processes, ensuring optimal purity and consistency for industrial customers.

Ressource Cavin ensures timely and efficient bulk shipping of Ethylene Glycol to meet the demands of our global clients.

⚙️ Méthode de production

Ethylene Oxide Hydration

1. Ethylene is oxidized to form ethylene oxide

2. Ethylene oxide is then hydrated to form monoethylene glycol (MEG)

3. Purified via distillation and filtration to meet specific grade standards

❓ Foire aux questions (FAQ)

1. Is Ethylene Glycol toxic?

Yes. While it has a sweet taste, ethylene glycol is toxic if ingested, particularly by humans and animals. Proper handling and labeling are essential.

2. What is the difference between MEG and DEG?

Monoethylene Glycol (MEG) is used in antifreeze and polyester, while Diethylene Glycol (DEG) is more common in solvents and humectants.

3. Is Ethylene Glycol biodegradable?

Yes, ethylene glycol is biodegradable under aerobic conditions, but spills should still be properly contained and cleaned.

4. Can it be used in HVAC systems?

Yes. Ethylene Glycol is widely used in chillers, heat exchangers, and HVAC equipment as a coolant.
