What is Ethylene glycol？

Ethylene glycol is the simplest member of the glycol family, characterized by its high boiling point, low volatility, and excellent water solubility. It is a vital industrial chemical with widespread applications due to its hygroscopicity and ability to lower the freezing point of water. Primarily known for its use in antifreeze and coolant formulations, it also serves as a key raw material in the production of polyesters, resins, and various other chemical intermediates.
