Product type
Diethylene glycol (DEG) is a colorless, odorless, and hygroscopic organic compound that belongs to the glycol family. It is produced through the hydration of ethylene oxide and is known for its ability to absorb moisture. DEG is commonly used as a solvent, plasticizer, and as an intermediate in the production of various chemicals. Its properties make it suitable for applications in antifreeze formulations, hydraulic fluids, and in the production of resins and adhesives.

When selecting diethylene glycol, consider the intended application and required purity levels. Buyers should specify the desired grade, as DEG can vary in purity and may have different specifications based on its use in industrial applications. Additionally, inquire about the availability of safety data sheets and any relevant certifications that may be necessary for compliance with industry standards.
