Product type
Triethylene glycol (TEG) is a colorless, odorless liquid that is hygroscopic and has a high boiling point. It is produced through the polymerization of ethylene oxide and is commonly used as a solvent, plasticizer, and in the formulation of various chemical products. TEG is known for its ability to absorb moisture, making it effective in applications requiring dehumidification and as a drying agent.
