乙二醇

CAS No.: 107-21-1

Usage: MEG finds many industrial diverse 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 familys solvency

properties are useful in custom formulation of paints, dyes, inks and other blended

products.
