Monoethylene glycol

Monoethylene Glycol – Essential Solvent for Industrial Use

Monoethylene Glycol — or MEG, as it’s often known in the industry — is one of those unsung heroes quietly powering a surprising number of processes behind the scenes. It’s a clear, practically odourless liquid, water-soluble, and widely used across a range of Australian industries. You’ll find it in everything from antifreeze to polyester fibres, and even flowing through the pipes of industrial cooling systems. If you’re looking for a reliable chemical supplier in Perth, we offer high-quality Monoethylene Glycol tailored for both large-scale operations and more specialised applications.

So… What Exactly Is Monoethylene Glycol?

At its core, Monoethylene Glycol (MEG) is a moderately viscous, hygroscopic liquid — which basically means it loves water. Its chemical formula is C₂H₆O₂, and it’s usually produced by hydrating ethylene oxide. MEG stands out for its strong solvent properties and high boiling point, making it incredibly versatile.

In some parts of the world, especially in the U.S., people might call it just “ethylene glycol.” But when we say Monoethylene Glycol, we’re talking about the pure, unblended stuff — no additives, no confusion. Because it mixes completely with water and doesn’t easily evaporate, it’s excellent in systems that need moisture retention, thermal stability, or low freezing points. Simple, but powerful.

How It’s Actually Used

• Antifreeze & Coolants: You’ve probably heard of this one. Monoethylene Glycol is a go-to chemical for lowering the freezing point and raising the boiling point of water — essential for car engines, pipeline systems, and HVAC loops. It keeps systems running smoothly, even in extreme temperatures.
• Polyester Fibre Production: MEG plays a crucial role in making PET — that’s polyethylene terephthalate — used in plastic bottles and textiles. Without it, many everyday products would be, well… not here.
• Dehydration of Natural Gas: In gas treatment, MEG helps by absorbing water and preventing hydrate formation in pipelines.
• Paints, Inks & Resins: Thanks to its solvency, it’s a preferred ingredient in resins, coatings, and inks. It helps maintain consistency and keeps moisture levels where they should be.
