Ethylene glycol
Product Description
Ethylene glycol is also known as glycol, 1,2-ethylene glycol, or EG for short. The chemical formula is (CH2OH)2, which is the simplest diol. Ethylene glycol is a colorless, odorless, sweet liquid with low toxicity to animals. Ethylene glycol is miscible with water and acetone, but its solubility in ethers is small. Used as solvent, antifreeze and raw material for synthetic polyester.

Applications / Usages
Mainly used to make polyester, polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, and used as a solvent for dyes and inks, antifreeze for engines, and gas dehydrating agents , Manufacture of resin, can also be used in cellophane, fiber, leather, adhesive wetting agent. It can produce synthetic resin PET, fiber-grade PET that is polyester fiber, bottle-grade PET for making mineral water bottles, etc. It can also produce alkyd resin, glyoxal, etc., and is also used as an antifreeze agent. In addition to being used as an antifreeze agent for automobiles, it is also used for the transportation of industrial cooling capacity. It is generally called a brine. At the same time, it can also be used as a condensing agent like water.
Packaging &Shipping
Packed in galvanized iron drum, 100Kg or 200Kg per drum. It should be sealed during storage, and hydrogen-sealed, moisture-proof, fire-proof, and freeze-proof should be used for long-term storage. Store and transport according to the regulations of flammable chemicals.
