APPLICATIONS

Ethylene glycols find many diverse industrial uses which include freeze protection, heat transfer and hydraulic fluids; natural gas and hydrocarbon treating agents; hydroscopic agents for paper, cork and textile conditioning; plasticizer formulations and raw materials for ester and polyester production. The ethylene glycol family’s solvency properties are useful in custom formulation of paints, dyes, inks and other blended products.
