Description

Chemical Properties:

Ethylene glycol is a colorless, viscous, hydroscopic liquid with a sweetish taste. Often colored fluorescent yellow-green when used in automotive antifreeze. Ethylene glycol is odorless and does not provide any warning of inhalation exposure to hazardous concentrations. The Odor Threshold in the air is 25 ppm.

Application:

  • Mainly used for making polyester fiber, polyester resin, dehumidifying agents, plasticizers, surfactants, and synthetic fibers.
  • Can be used as a dye/ink solvent, in the preparation of engine antifreeze, and gas dehydration.
  • For the production of synthetic resin, PET, or polyester fiber grade PET, bottle-grade PET film is used to produce mineral water bottles.
  • Can also produce alkyd resins, also used as antifreeze.
