Glycol-Based Industrial Chemicals / Solvents & Humectants

Description

Diethylene Glycol (DEG) is a clear, colorless, hygroscopic liquid widely used as a solvent, humectant, and chemical intermediate. Known for its excellent hygroscopicity, high boiling point, and complete miscibility with water and many organic solvents, DEG is used across chemical, cosmetics, plastics, resins, and textile industries. It serves as a key ingredient in the production of polyester resins, plasticizers, and brake fluids and is widely utilized as a dehydrating agent and solvent in formulations.

Applications

• Polyester Resin Production: Raw material for polyesters & alkyd resins
• Plasticizers: Manufacture of flexible PVC plasticizers
• Solvent: Used in dyes, inks, oils, resins, and lubricants
• Humectant: Moisture-retaining agent in industrial formulations
• Automotive Fluids: Component in brake fluids & coolants
