| Uses | Ethylene glycol is used to make polyester, polyester resin, moisture absorbent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, as a solvent for dyes, inks, etc., to prepare engine antifreeze, and gas dehydration It can also be used as a wetting agent for cellophane, fiber, leather and adhesives in the manufacture of resins. It can produce synthetic resin PET, fiber-grade PET or polyester fiber, and flake-grade PET for making mineral water bottles. It can also produce alkyd resin, glyoxal, etc., and also be used as an antifreeze. In addition to being used as an antifreeze for automobiles, it is also used for the transportation of industrial refrigeration. It is generally called a refrigerant carrier. | ||
