CharacteristicsPolyethylene glycols are obtained as a result of mixing unpurified fractions formed during the process of ethylene glycols production. The mixture contains chiefly diethylene and triethylene glycol (DEG and TEG). PEG can also contain mechanical and mineral impurities (salts).
ApplicationsAs a precursor for making anti-freezing preparations, and for increasing viscosity of specialised liquids. It is used particularly when the purity of glycol is not of special importance.
