High-Quality Mono Ethylene Glycol (MEG)
Mono Ethylene Glycol (MEG), also known as ethylene glycol, is an industrial dihydric alcohol with the molecular formula C₂H₆O₂ (CAS 107-21-1).
It is widely used as a basic chemical raw material in polyester production, antifreeze formulations, heat transfer fluids, and chemical synthesis systems.
Specifications of Mono Ethylene Glycol (MEG)
- Fiber grade: purity ≥99.9%
- Industrial grade: purity ≥99.0%
- Antifreeze grade: purity ≥95.0%
- Density: ~1.113 g/cm³ (20°C)
- Boiling point: 197.3°C
- Freezing point: -12.6°C
In industrial applications, mono ethylene glycol meg purity and moisture content directly affect polymerization stability in polyester production and freezing performance in coolant systems.

mono ethylene glycol production process
MEG is commonly produced via ethylene oxide hydration process, a standard industrial route used in large-scale chemical production.
This process allows controlled conversion efficiency and stable batch-to-batch quality when combined with industrial distillation and purification systems.
Quality Control and Documentation
Each batch of ethylene glycol is typically supplied with standard industrial documentation, including:
- COA (Certificate of Analysis): purity, moisture, density, and key physical parameters
- MSDS (Safety Data Sheet): chemical hazards, handling, and storage information based on GHS standards
- TDS (Technical Data Sheet): application and technical specification guidance
These documents support industrial procurement, import clearance, and safety compliance requirements.
Transportation and Compliance
MEG is classified as a regulated chemical for transport under international standards.
Packaging and logistics compliance may include:
- UN-certified packaging for hazardous chemical transport
- Hazard classification documentation
- Compliance with international chemical regulations such as REACH (EU) and TSCA (US), where applicable
Transportation methods include sea freight, air freight, and land transport depending on destination requirements.
Supply and Service Capabilities
Tianjin Gnee Biotech Co., Ltd. supplies industrial MEG with stable production capacity and standardized export packaging for global chemical procurement.
Factory-based production ensures batch-to-batch consistency, with fiber-grade MEG controlled at ≥99.9% purity compared with industrial-grade MEG at ≥99.0%, which is commonly used for general chemical applications.
Export packaging is available in 200 kg steel drums and ISO tank containers, where ISO tanks are typically used for bulk shipments above 20,000 kg to reduce per-ton logistics cost.
International logistics covers sea, air, and land transport, with sea freight accounting for more than 80% of bulk chemical shipments due to lower cost per ton compared with air freight.
Supply conditions depend on order specification, where higher-purity MEG requires stricter moisture control typically below 0.05% in fiber-grade applications.
Mono Ethylene Glycol Market Applications
MEG is mainly consumed in polyester production, which accounts for more than 87% of global industrial demand.
In antifreeze systems, MEG reduces the freezing point from 0°C (water) to -12.6°C, making it suitable for automotive cooling and industrial refrigeration systems.
In heat transfer applications, MEG remains thermally stable up to 197.3°C boiling point, compared with ethanol at 78.3°C, allowing wider operating temperature ranges.
In coatings and resin systems, MEG is fully miscible with water and polar solvents, improving formulation stability in water-based systems compared with non-polar solvents such as hydrocarbons.
In chemical synthesis, MEG is used as an intermediate for glycol ethers and polyester production due to its two hydroxyl (-OH) groups, which enable controlled reactivity in polymerization processes.
Conclusion
Mono Ethylene Glycol (MEG) is a widely used industrial chemical with stable physical and chemical properties, commonly applied in polyester manufacturing, antifreeze systems, and industrial chemical processing.
Tianjin Gnee Biotech Co., Ltd. is a manufacturer and supplier of MEG, providing global customers with standardized product documentation, consistent production quality, and export logistics support.
