Ethylene Glycol 30/70

Product Overview

Ethylene Glycol 30/70 is a precise solution of 30% ethylene glycol (C₂H₆O₂) and 70% water, manufactured to Laboratory Grade standards. Also known as Monoethylene Glycol (MEG) or industrial antifreeze, this concentration is optimized for heat transfer efficiency in closed-loop systems where freeze protection and thermal stability are critical. The solution appears as a clear, colorless liquid and is pre-mixed to ensure accurate concentration without the need for on-site dilution.

This formulation is widely utilized in HVAC systems, industrial chillers, and chemical processing equipment. Its thermal properties allow for effective heat removal while the high purity profile minimizes the introduction of contaminants like chlorides or heavy metals into sensitive piping systems. Ethylene Glycol 30/70 maintains fluidity at lower temperatures compared to water alone, making it essential for equipment exposed to varying environmental conditions.

Common Applications

• HVAC & Chiller Systems: Functions as a primary heat transfer fluid in commercial and industrial air conditioning loops.
• Industrial Antifreeze: Provides freeze protection for closed-loop water systems in cold environments.
• Chemical Processing: utilized as a solvent and thermal fluid in reactor jackets and process cooling lines.
• Laboratory Research: Acts as a consistent, high-purity thermal medium for benchtop heating and cooling baths.
• Manufacturing: Used as a dehydrating agent or solvent in the production of resins and plastics.

Safety Precautions

Store Ethylene Glycol 30/70 in a cool, dry area away from direct sunlight. Ensure storage containers are compatible materials such as HDPE or stainless steel. This product acts as a central nervous system depressant if ingested; do not use in food, beverage, or potable water systems. Wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles, during handling to prevent skin and eye contact. Refer to the Safety Data Sheet (SDS) for detailed emergency and disposal procedures.

Benefits

Pre-Mixed Convenience – 30/70 ratio ensures consistent concentration and eliminates mixing errors on-site.
