CAS 107-21-1 Ethylene glycol is not the same as antifreeze, but it is a key active ingredient in most antifreeze formulations. Antifreeze is a ready-to-use or concentrated fluid designed to protect engines and cooling systems, and its primary functional component is often ethylene glycol (or sometimes propylene glycol, a less toxic alternative). Pure ethylene glycol is a viscous liquid, so antifreeze blends it with water (typically in a 50:50 ratio) to optimize its freezing/boiling point properties and improve heat transfer.
Ethylene Glycol (MEG) For Coolant / Antifreeze
In car antifreeze formulations, ethylene glycol effectively prevents engines from freezing in winter and overheating in summer. When mixed with water (typically in a 50:50 ratio), it depresses the freezing point to about minus 35°C while raising the boiling point, ensuring optimal engine performance year-round. Combined with the corrosion-inhibiting additives, the coolant /antifreeze solution protects radiators, pipes, and other metal components from corrosion, extending the lifespan of vehicle cooling systems.
