Triethylene Glycol

Triethylene glycol (TEG) is a widely used glycol compound valued for its strong solvency, humectant properties, low volatility, and thermal stability. It is an essential chemical in industrial, consumer, and specialty applications, particularly where moisture retention, chemical compatibility, and heat transfer performance are required. Its hygroscopic nature makes it highly effective as a dehydrating agent, while its stability allows it to perform reliably in demanding manufacturing environments.

In industrial applications, triethylene glycol is extensively used in natural gas dehydration, heat transfer fluids, and antifreeze formulations, where its high boiling point and efficiency ensure consistent performance. In consumer and specialty markets, TEG is applied in coatings, adhesives, cosmetics, and pharmaceuticals as a solvent, carrier, and humectant. It is also used in the production of polyester resins, plasticizers, and chemical intermediates, supporting polymer and specialty chemical manufacturing. With its balance of versatility, effectiveness, and safety, triethylene glycol remains a critical raw material across industries including automotive, construction, energy, personal care, and healthcare.
