Introducing of the ethylene glycol

Specifications of the ethylene glycol

Monoethylene glycol is mainly used as a car antifreeze and coolant, and also as a raw material for the production of polyethylene terephthalate (PET) in different grades of fibers, sheets, films and bottles. This substance is also used as a heat transfer fluid, a solvent for cellulose esters and ethers, especially cellophane, in the cosmetic industry, alkyderzins, glycol ethers, printing inks, adhesives, foam stabilizers, and one of the components of anti-icing liquid in covering the runway surface of airports, emulsions Asphalt, the production of capacitors, latex paints, the production of unsaturated polyester resins and glycol diacetate, as well as the raw material in the production of ethylene glycol dinitrate for use in freezing dynamite at low temperatures are used.
