1,2-ethanediol; Ethylene glycol (MEG)
CAS Number: 107-21-1
Formula: C2H6O2
DESCRIPTION:
Monoethylene glycol is a clear, colorless and hygroscopic liquid, withmoderately viscous. It is completely miscible with water and manyorganicliquids
APPLICATION:
Monoethylene glycol (MEG) is most commonly used as chemical intermediate in the manufacture of polyester resins and textile fibers. MEGisalso wildly used as automotive antifreeze due to its low freezingpoint whenmixed with water and used as heat transfer fluids for ventilationandair-conditioning systems

REGULATORY INFORMATION:
IMDG Classification: Non-Dangerous Goods
HMIS Code: 2-1-0
HS Code: 2905.31.00
HANDLING AND STORAGE:
Keep the material in the anhydrous state to prevent severe corrosiontothecarbon steel or aluminum tank and related equipment. For longer termcolorstability, it is recommended that the product be stored under aninertatmosphere.
Monoethylene glycol products have 24 months of shelf-life timeunderunopened drum. The product should be re-evaluated after 24monthstoreconfirm the product quality, if properly stored and protectedfromcontamination. For bulk container, the shelf-life time of product is 6monthsfrom manufacturing date.
For storage conditions, product is hygroscopic, water contaminationshouldbeavoided. Keep container tightly closed without air contamination. DuetoMonoethylene glycol is very sensitive with moisture, an elevated moisturelevel when do re-sampling might be faced. The periods of exposuretohightemperatures should be minimized. Avoid directly contact with sunlight andhigher temperature. Monoethylene glycol is recommended to be storedunderan inert atmosphere such as nitrogen blanket to sustain product stability.
PACKAGING:
Product is available in bulk truck, ISO Tank, flexi bag, IBC tank, steel drumwithepoxy phenolic coating. Recommended containers are stainless steel andaluminum or carbon steel with suitably lined. IBC tank material shouldbeHDPEwith UV stabilized and opaque to prevent UV degradation. Certain governmentregulations may apply at the time of shipment and delivery.
SAFETY:
Wear appropriate personal protective equipment, includingappropriaterespiratory protection. Avoid contact with skin, eyes or clothing. For informationon the toxicity and handling of this product, please find in the Material SafetyData Sheet.
