Application
1.Ethylene glycol mainly used for making polyester, polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives.
2.It is also used as solvent for dyes, inks, antifreeze for engine preparation, gas dehydrating agent, resin manufacturing, and wetting agent for cellophane, fiber, leather and adhesive. It can produce synthetic resin pet, fiber grade PET is polyester fiber, bottle grade PET is used to make mineral water bottle, etc.
3.It can also produce alkyd resin, glyoxal, etc. it can also be used as antifreeze. In addition to being used as antifreeze for automobile,.
4.it is also used for the transportation of industrial cooling capacity, which is generally called refrigerant. At the same time, it can also be used as condensing agent like water.
