Ethylene Glycol (EG), also known as Monoethylene Glycol (MEG), is a cornerstone chemical in a vast array of industrial processes. Its unique properties, including a low freezing point and high boiling point, coupled with its colorless and odorless viscous nature, make it an exceptionally versatile compound. NINGBO INNO PHARMCHEM CO.,LTD. is a key provider of this essential chemical, understanding its critical impact on manufacturing and consumer products worldwide.

One of the most significant applications of ethylene glycol is in the production of polyester. It serves as a primary monomer that reacts with terephthalic acid (PTA) to create polyethylene terephthalate (PET). PET is the foundation for polyester fibers, widely used in textiles, and polyester bottle chips, essential for beverage containers and films. The demand for high purity anhydrous ethylene glycol is particularly strong in this sector to ensure the quality and performance of the final polyester products.

Beyond textiles and packaging, ethylene glycol is indispensable as an antifreeze and refrigerant. Its ability to significantly lower the freezing point of water makes it the principal ingredient in automotive antifreeze. This application is crucial for preventing engine damage in cold weather and maintaining optimal operating temperatures. Similarly, its thermal stability makes it suitable for industrial cooling systems and as a heat transfer medium. The need for industrial grade antifreeze ensures efficient and reliable performance across various demanding environments.

Ethylene glycol also functions as a vital chemical intermediate. It is used in the synthesis of other important chemicals such as glyoxal, oxalic acid, and even components for polyurethane production. Its properties as a solvent further broaden its utility, including in specialized applications like cleaning photoresists in the electronics industry. The availability of ethylene glycol for lithium battery electrolyte highlights its role in emerging energy technologies.

For those looking to secure a reliable supply, understanding the available product grades, such as polyester grade ethylene glycol or high-purity anhydrous forms, is key. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of proper handling and storage, referencing technical data sheets like the ethylene glycol MSDS for safety guidelines. Adhering to ethylene glycol storage requirements ensures product integrity and safety. The ethylene glycol CAS number, 107-21-1, is a universal identifier for this crucial chemical. Companies often search to buy ethylene glycol online, seeking suppliers who offer consistent quality and robust logistical support to meet their production schedules.
