Products Description
What is Monoethylene Glycol (MEG)?
Mono Ethylene Glycol, commonly abbreviated as MEG or simply ethylene glycol, is a colorless, odorless, hygroscopic liquid with the chemical formula C2H6O2. It is fully miscible with water and many organic solvents, and is best known as the key raw material for producing polyester (PET) fiber, PET resin for bottles and packaging, and polyester film. Beyond the polyester industry, MEG is widely used as the main component of antifreeze and coolant fluids, as a heat transfer medium, and as a chemical intermediate for unsaturated polyester resins. Depending on purity and impurity control (such as diethylene glycol and UV transmittance), MEG is generally supplied as fiber grade for textile applications or industrial grade for antifreeze, solvent, and general chemical uses.

Applications of Monoethylene Glycol :
- Primary raw material for polyester (PET) fiber, PET resin for bottles/packaging, and polyester film production
- Main active ingredient in automotive and industrial antifreeze and coolant fluids
- MEG is used as a heat transfer fluid in HVAC and industrial cooling systems
- Chemical intermediate for unsaturated polyester resin (UPR), used in coatings and fiberglass composites
- Used as a solvent and humectant in various industrial and chemical processes
- Used as an aircraft and runway deicing fluid component
Storage & Handling
- Store in a cool, dry, well-ventilated warehouse, away from strong oxidizing agents and direct sunlight
- MEG is hygroscopic; keep containers tightly sealed to prevent moisture absorption, which can affect quality in fiber-grade applications
- Non-flammable under normal handling conditions (flash point 111°C), but toxic if ingested; keep away from food, feed, and drinking water sources
- Use appropriate PPE (gloves, goggles) during handling and follow the SDS for spill and exposure procedures
- Recommended shelf life: 24 months from production date when stored under proper sealed conditions

FAQ
Q1: What is MEG mainly used for?
A1: Monoethylene Glycol MEG is mainly used as the raw material for polyester (PET) fiber, PET resin, and polyester film, and as the main component of antifreeze/coolant fluids and heat transfer fluids.
Q2: What is the difference between fiber grade and industrial grade MEG?
A2: Fiber grade MEG has tighter controls on UV transmittance, color, and impurities such as diethylene glycol and aldehydes, since these affect polyester fiber and PET resin quality. Industrial grade MEG has more relaxed specifications and is typically used for antifreeze, solvent, and general chemical applications.
Q3: Can MEG (CAS 107-21-1) be shipped in bulk, such as ISO tanks or flexitanks?
A3: Yes, for regular buyers we recommend ISO tank containers or flexitanks, which are usually more cost-effective than drums for volumes above roughly 18-20 MT per shipment. Bulk vessel shipment can also be arranged for very large volume contracts.
Q4: Can you provide COA and SDS for each shipment?
A4: Yes, COA and SDS are provided with every order, and batch-specific COA can be issued for your reference before or after loading.
Q5: Can MEG be blended with other glycols for antifreeze formulations?
A5: Yes, MEG is commonly blended with corrosion inhibitors and, in some formulations, with propylene glycol to adjust toxicity or freezing-point performance. We recommend confirming your specific formulation ratio and additive package with your R&D or formulation team.
