Product Description

It is colorless obvious viscous liquid with candy style and moisture absorption capability. It is additionally miscible with water, low-grade aliphatic alcohols, glycerol, acetic acid, acetone, ketones, aldehydes, pyridine and comparable coal tar bases. It is barely soluble in ether however nearly insoluble in benzene and its homologues, chlorinated hydrocarbons, petroleum ether and oils.

Product Usage

Ethylene glycol is a colorless, odorless, and sweet-tasting liquid primarily valued for its dual functionality as a coolant and a chemical precursor. Its most widespread application is as the primary ingredient in automotive antifreeze and coolants, where it lowers the freezing point and raises the boiling point of engine fluids. In the plastics industry, it is a critical raw material for producing polyethylene terephthalate (PET), used for beverage bottles and polyester fibers. Additionally, it serves as an effective de-icing agent for aircraft and runways and acts as a humectant in the textile and paper industries.
