Purpose:
It is mainly used to make polyester polyester, polyester resin , hygroscopic agent, Plasticizer , surfactant, synthetic fiber, cosmetics, and used as dyestuff Solvent for printing ink, 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, and bottle slice grade PET is used to make mineral water bottles. It can also produce alkyd resin and be used as antifreeze. In addition to being used as antifreeze for automobiles, it is also used for the transportation of industrial cold energy, commonly called as refrigerant carrier. At the same time, it can also be used as a condensate like water.
Ethylene glycol series products are advanced organic solvents with excellent performance, which are used as solvents and diluents for printing inks, industrial cleaning agents, coatings (nitrocellulose paint, varnish, enamel), copper clad laminate, printing and dyeing, etc; Raw materials for synthetic brake fluid and other chemical products; As electrolyte of electrolytic capacitor, dyeing agent for leather making chemical fiber, etc. Used as textile auxiliaries, synthetic liquid dyes, and raw materials in chemical fertilizer and oil refining production.
