use

1. Mainly used to make polyester polyester, polyester resin, hygroscopic agent, 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.

2. It can also produce alkyd resin, glyoxal, etc., and also used as 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. At the same time, it can also be used as a condensation agent like water.

3. Ethylene glycol methyl ether series products are high-grade organic solvents with excellent performance, used as solvents and thinners for printing inks, industrial cleaning agents, coatings (nitrocellulose paint, varnish, enamel), copper clad laminates, printing and dyeing, etc.

4. It can be used as a raw material for the production of pesticide intermediates, pharmaceutical intermediates and synthetic brake fluids and other chemical products; as an electrolyte for electrolytic capacitors, as a leather-making chemical fiber dye, etc.

5. Used as textile auxiliaries, synthetic liquid dyes, and raw materials for desulfurization agents in fertilizer and oil refining production.
