ELECTRONIC GRADE PROPYLENE GLYCOL MONOMETHYL ETHER

Propylene Glycol Methyl Ether and Ethylene Glycol Ether belong to the same class of diol ether solvents. The toxicity of Propylene Glycol Ether to human body is lower than that of Ethylene Glycol Ether products, which belongs to low toxicity ether class. Propylene Glycol Methyl Ether has a weak ether flavor but no strong irritating odor, which makes it more widely and safely used. Because of its molecular structure has both ether group and hydroxyl group, its solubility performance is very excellent, and it has suitable volatilization rate and reaction activity and other characteristics to obtain broad application.
