Polypropylene Glycols (PPGs)
Polypropylene glycols are polymers of propylene oxide. They are clear, viscous liquids with low pour points. Viscosity increases and water solubility decreases with increasing molecular weight.
DOW P-series polyglycols are linear polymers containing two terminal hydroxyl groups. DOW PT-series polyglycols are glyceryl ether polymers containing three terminal hydroxyl groups.
