Your Guide to Triethylene Glycol (TEG): Specs, Uses & Supply

Get reliable TEG sourcing for chemical manufacturing and oil & gas.

What is Triethylene Glycol?

Triethylene Glycol (TEG) might not be a household name, but in the industries that rely on it, it’s indispensable. Known for its high boiling point, hygroscopic properties, and ability to absorb water, TEG plays a critical role in chemical manufacturing and natural gas dehydration. Without it, pipelines would be less efficient and chemical processes would be harder to manage. 

That’s where Meadows Chemical comes in. As a supplier who knows that “on time” and “on spec” aren’t just buzzwords, we’ve built a reputation for pairing customers with the exact grade of TEG they need—without the wait times, pricing headaches, or logistical roadblocks that slow down operations. Whether you’re in the chemical sector or the oil & gas industry, we deliver solutions that fit your timelines and your bottom line.

Key Uses of Triethylene Glycol

TEG is highly versatile, with properties that make it both a powerful solvent and a reliable dehydrating agent. Its ability to hold up under pressure—literally—is why it’s a must-have in industries that demand consistency.

Chemical Manufacturing

In chemical production, TEG is valued as a solvent, plasticizer, and intermediate. Its stability and low volatility make it an excellent carrier for formulations, while its solvency properties allow it to blend seamlessly in resins, coatings, and specialty chemicals. From adhesives to cosmetics, TEG helps manufacturers produce materials that meet performance and durability standards without compromising on cost efficiency.

Oil & Gas

TEG is best known in the oil & gas industry for its role in natural gas dehydration. By removing water vapor from raw natural gas, TEG prevents pipeline corrosion, hydrate formation, and flow interruptions, keeping operations safe, efficient, and compliant. Its high boiling point ensures reliability in harsh processing environments, making it the go-to choice for gas plants and refineries across the globe.
