Ethylene Glycol Inhibited ACS Grade

Product Overview

Ethylene Glycol Inhibited ACS Grade is a high-purity, colorless liquid formulated with specific additives to prevent corrosion and scale in metal systems. While standard Ethylene Glycol (also known as MEG or Monoethylene Glycol) is naturally corrosive to metals over time, this inhibited formulation extends the lifespan of industrial equipment, cooling loops, and heat transfer systems.

Meeting ACS Reagent Grade specifications, this product guarantees high purity (Assay 99.0–100.5%) and low water content, making it suitable for critical laboratory applications and precise industrial formulations. It features a high boiling point and low freezing point, ensuring thermal stability across a wide temperature range. The product is widely used in chillers, boilers, and closed-loop systems where maintaining system integrity is paramount.

Key Properties

• CAS Number: 107-21-1
• Formula: C₂H₆O₂

Common Applications

• Heat Transfer Fluid: Used in industrial chillers, HVAC systems, and geothermal loops to transfer heat efficiently while protecting pipes from corrosion.
• Antifreeze & Coolant: Depresses the freezing point of water in closed-loop systems, preventing burst pipes and freezing damage in cold environments.
• Chemical Solvent: Acts as a reliable solvent in chemical synthesis and resin manufacturing due to its miscibility and stability.
• Hydraulic Fluid: Utilized in hydraulic equipment requiring a high boiling point and consistent viscosity under pressure.
• Laboratory Reagent: Employed in research and analytics requiring ACS grade purity and traceable specifications.

Safety Precautions

Ethylene Glycol is toxic if swallowed. Handle with care using appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles. Use in a well-ventilated area to avoid inhalation of vapors. Store in a cool, dry place away from direct sunlight and incompatible materials like strong oxidizers. In the event of a spill, contain with absorbent material and dispose of in accordance with local regulations.

Benefits

• Corrosion Protection: Inhibited formula prevents rust and degradation in metal piping and system components.
• ACS Grade Purity: High assay ensures consistent performance in sensitive industrial and analytical applications.
• Thermal Stability: Excellent heat transfer properties with a broad operating temperature range.
