Description

Diethylene Glycol is a versatile and widely used industrial chemical, a member of the glycol family prized for its hygroscopic nature and excellent solvent properties. Its ability to absorb moisture and blend with water, alcohols, and many organic compounds makes it a critical component in numerous manufacturing processes. This product is essential for industries ranging from polymers and resins to natural gas processing and textile manufacturing, where consistent quality and reliable supply are paramount.

Application

• Natural Gas Dehydration: A key component in hygroscopic triethylene glycol (TEG) systems for removing water vapor from natural gas streams.
• Polymer & Resin Production: Acts as a plasticizer and intermediate in the manufacture of unsaturated polyester resins (UPR) and polyurethanes.
• Solvent & Carrier Fluid: Used in printing inks, textile dyes, adhesives, and as a solvent for nitrocellulose and other resins.
• Humectant & Conditioning Agent: Employed in paper, leather, and tobacco processing to retain moisture and improve flexibility.
• Chemical Intermediate: Serves as a building block for the synthesis of morpholine, esters, and other specialty chemicals.
• Hydraulic & Brake Fluid Formulations: Used in some formulations for its lubricating and moisture-control properties.
• Heat Transfer Fluid: Utilized in closed-loop heating and cooling systems due to its low freezing point and high boiling point.

Quality Control

Our Diethylene Glycol is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive quality assurance, with products meeting relevant industrial and technical grade specifications. A Certificate of Analysis (COA) detailing purity, assay, and key impurity profiles is available for every shipment upon request, supporting your quality and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers should be kept tightly sealed when not in use to prevent absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
