Ethylene Glycol® (MEG)

Description

• High-purity technical antifreeze fluid used in building engineering, heat recovery systems, and as a coolant in vehicles.
• In industrial environments, ethylene glycol is more widely used due to its lower purchase cost, lower viscosity resulting in reduced operating costs (lower pump consumption), and superior heat transfer properties.
• Ethylene glycol is toxic and classified as a hazardous substance under REACH regulations; therefore, its use requires increased attention to workplace safety.

Specification

• Freezing point: -70 °C
• Boiling point: 197.3 °C
• Density: 1.1132 g/cm³
• Viscosity: 16.1 mPa·s

• The freezing point is not directly proportional to dilution.

• A mixture of 1 part water and 1 part ethylene glycol has a freezing point of -37 °C.

• Excellent corrosion resistance and high thermal stability.

• Recommended replacement interval: 2–3 years.

General Applications

• Chemical raw material
• Heat transfer medium
• Coolant mixtures
• De-icing agents
• Polymer fiber production
• Paint industry
• Detergent manufacturing
• Metal processing
• Agrochemicals
• Water treatment
• Lubricants

• Use of propylene glycol is not recommended in systems designed for ethylene glycol, as its higher viscosity may alter pump performance and reduce cooling efficiency.
