Diethylene Glycol (DEG) CAS 111-46-6 High Purity Factory Direct, Good Quality Low Price, Fast Delivery

• Ⅰ.Product Overview
• 
  
• ⭐Diethylene Glycol (DEG) (CAS 111-46-6) is an important aliphatic diol. It appears as a colorless, transparent and viscous liquid with no peculiar odor and stable chemical properties, and the purity can reach over 99.5% (industrial grade). As a rigid demand industrial raw material, it has excellent solubility, moisturizing property and antifreeze performance, and is miscible with most solvents such as water and ethers. Widely used in chemical synthesis, solvent dilution, textile moisturizing, industrial antifreeze and other fields, it is a core raw material for producing polyester resins, glycol ethers and rubber plasticizers. Meanwhile, it can be used as a moisturizing auxiliary in textile and papermaking industries, suitable for multi-scenario industrial production. With stable supply and excellent cost performance.
