What are the different grades of ethylene glycol?

Ethylene Glycol EG is graded mainly by purity and application, with Mono Ethylene Glycol (MEG) as the most common type.

 

Industrial Grade EG has 99.5-99.9% purity, used for antifreeze and coolants.

 

Fiber Grade EG is high-purity for polyester and PET plastic production.

 

USP/Pharmaceutical Grade EG has purity over 99.9% and ultra-low diethylene glycol content.

 

Technical Grade EG has about 95% minimum purity for general industrial use.

 

Reagent Grade EG is high-purity for lab and analytical work.
