Ethylene Glycol (MEG, DEG, TEG & TTEG)
Ethylene Glycol is derivative of Ethylene oxide and it is used for the main in Polyester manufacturing for fiber and PET application. And can be used for chemical intermediates for resins, solvent couplers, freezing point depression, brake fluids, solvents, humectants and chemical intermediates. These applications are vital to the manufacture of a wide range of products, including PET resins; deicing fluids; heat transfer fluids; automotive antifreeze and coolants; water-based adhesives, latex paints, oil & gas dehydration and asphalt emulsions; electrolytic capacitors; textile fibers; paper and leather.
