Introduction
Ethylene glycol, also known as glycol, is an important organic chemical raw material with a wide range of uses.
1. In the field of polyester fibers and polyester plastics
Production of polyester fibers: Ethylene glycol can react with terephthalic acid (PTA) to produce polyester fibers such as polyester. Polyester fibers have the advantages of high strength, wear resistance, and wrinkle resistance, and are widely used in fields such as clothing, home textiles, and industrial fabrics.
2. In the field of antifreeze and coolant
As automotive antifreeze: Ethylene glycol has a low freezing point and a high boiling point, and can effectively prevent the engine cooling system from freezing at low temperatures and boiling at high temperatures. It can protect the engine to operate normally under various climatic conditions.
3. In the field of chemical raw materials
Production of other chemicals: Ethylene glycol can be used as a raw material to produce a variety of chemicals, such as ethylene glycol ethers, polyurethanes, unsaturated polyester resins, etc.
