Description
It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid.
End uses for MEG range from clothing and other textiles, through packaging to kitchenware, engine coolants and antifreeze. Polyester and fleece fabrics, upholstery, carpets and pillows, as well as light and sturdy polyethylene terephthalate drink and food containers originate from ethylene glycol. The humectant (water attracting) properties of MEG products also make them ideal for use in fibres treatment, paper, adhesives, printing inks, leather and cellophane.
MEG is produced from ethylene via ethylene oxide, which in turn is hydrated by using either a thermal or catalytic production process.
