About Monoethylene Glycol
Monoethylene Glycol is a colorless, odorless, and hygroscopic liquid with a sweet taste. It is the simplest glycol and is widely used as a raw material in polyester manufacturing. Its properties as a solvent, humectant, and freezing point depressant make it essential in numerous industrial and consumer applications.
Applications / Uses
MEG is extensively used in chemical, textile, and automotive industries:
- Polyester Production: Key raw material in producing PET resins and polyester fibers for textiles and packaging.
- Antifreeze & Coolants: Main ingredient in engine coolants for automotive and industrial use.
- Deicing Fluids: Used in aircraft and runway deicers due to its low freezing point.
- Textiles: Acts as a humectant and softening agent in fabric treatment processes.
- Resins & Coatings: Used in alkyd resins and other coatings for enhanced durability and flow.
- Heat Transfer Fluids: Applied in solar panels, HVAC systems, and refrigeration for efficient heat exchange.
Storage & Handling
- Store in a tightly closed container in a dry, cool, and well-ventilated place.
- Avoid contact with strong oxidizing agents and moisture contamination.
- Use appropriate PPE including gloves, goggles, and protective clothing.
- Ensure good ventilation and avoid inhalation or prolonged skin contact.
