Diethylene Glycol

Diethylene Glycol (DEG) is a clear, colorless, and hygroscopic liquid with the chemical formula C4H10O3 and CAS number 111-46-6. It is a viscous organic compound widely employed as an intermediate in chemical manufacturing and as a solvent component in various industrial formulations. At Finstar Chemicals, this compound is supplied in standard industrial grades suitable for incorporation into antifreeze agents and plasticizer production, typically handled at ambient temperatures to avoid moisture absorption. The product is offered in packaging options including drums and Intermediate Bulk Containers (IBCs), facilitating procurement scalable for different operational demands. Buyers should be aware that Diethylene Glycol is incompatible with strong oxidizers and materials sensitive to moisture, necessitating storage in a cool, dry, well-ventilated area to maintain stability. Typical use rates vary depending on the application; for example, in antifreeze formulations, DEG content ranges from 10% to 40% by weight based on freezing point requirements.

In antifreeze and coolant formulations, Diethylene Glycol's role is to lower the freezing point of water-based fluids, preventing freezing and overheating conditions in engine cooling systems. Its hygroscopic nature ensures prolonged efficacy even in variable environmental temperatures by maintaining fluid viscosity and performance. Furthermore, DEG's solvent properties enable it to dissolve various compounds used in resin and plasticizer production, facilitating controlled chemical reactions and improving the quality of the final products. Reliable supply of DEG ensures uninterrupted manufacturing processes critical for industrial and automotive sectors.
