Monoethylene Glycol (MEG) — Brief Technical Overview

Monoethylene glycol is a clear, slightly viscous liquid used in polyester production and antifreeze formulations.

Chemical Identity

• Formula: C₂H₆O₂  
• Appearance: Clear, colorless, slightly viscous liquid  
• Solubility: Miscible with water, alcohols, and many organics 

Production

MEG is produced by hydrolyzing ethylene oxide, a reaction that yields MEG as the primary product along with smaller amounts of DEG and TEG. Modern plants use catalytic or thermal processes to maximize MEG selectivity.

Key Applications

• Polyester (PET) Production: Fibers, films, and packaging  
• Antifreeze & Coolants: Automotive and industrial heat‑transfer fluids  
• De‑icing & Anti‑icing: Aircraft and runway formulations  
• Chemical Intermediate: For solvents, surfactants, and glycols 

Why Industries Use It

• High purity and reactivity  
• Essential role in large‑scale polyester production  
• Strong performance in heat‑transfer applications  
• Reliable global demand and supply chain  

Availability

MEG is supplied by Tradella Company, meeting the needs of manufacturers across multiple sectors.
