WebEthylene Glycol Fluids (EG) In most applications, EG-based fluids are preferred because of their lower cost as well as lower viscosity and resulting superior heat transfer efficiency and pumping power. For cold systems, you can use ~2% less EG than PG to achieve the same freeze protection. Propylene Glycol Fluids (PG) This page provides supplementary chemical data on ethylene glycol.
