Description

Monoethylene Glycol (MEG) is a fundamental, high-volume industrial chemical and a primary member of the glycol family. Its exceptional properties as a versatile solvent, humectant, and antifreeze agent make it a critical raw material across numerous global manufacturing sectors. This product is essential for industries involved in the production of polyester resins and fibers, antifreeze and coolant formulations, and as a key intermediate in chemical synthesis.

Application

• Polyester Production: The primary industrial use as a monomer in the manufacture of polyethylene terephthalate (PET) for fibers, films, and plastic bottles.
• Antifreeze & Coolants: A major component in automotive and industrial engine coolants due to its ability to lower the freezing point of water.
• Chemical Intermediate: Used in the synthesis of various chemicals, including glycol ethers, unsaturated polyester resins (UPR), and plasticizers.
• Dehydrating Agent: Employed in natural gas processing to remove water vapor and prevent hydrate formation in pipelines.
• Solvent & Humectant: Acts as a solvent in paints, inks, and dyes, and as a humectant to retain moisture in products like adhesives and paper.
• Heat Transfer Fluids: Utilized in closed-loop heating and cooling systems for its thermal stability and heat capacity.

Quality Control

Our Monoethylene Glycol is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide material that meets or exceeds typical industry specifications for polyester-grade and industrial-grade applications. A comprehensive Certificate of Analysis (COA) detailing purity, water content, acidity, and other critical parameters is supplied with every shipment to guarantee compliance with your process requirements.

Storage

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