Description

Mono Ethylene Glycol (MEG) is primarily produced via the hydration of ethylene oxide, which itself is derived from petrochemical feedstocks like ethylene. It is hygroscopic in nature (absorbs moisture from air) and has excellent heat transfer properties, making it ideal for thermal systems.
