Chemical Profile

Product Overview

40% Propylene Glycol Inhibited is a ready-to-use, technical grade aqueous solution designed for optimal thermal transfer in industrial machinery and HVAC systems. Also known as MPG or Propane-1,2-diol, this formulation includes a robust inhibitor package that protects metals from corrosion, scaling, and fouling. Unlike uninhibited glycols, this product offers extended service life for equipment by stabilizing pH and preventing acidification during thermal cycling.

This 40% concentration balances freeze protection with heat transfer efficiency, making it an ideal coolant for closed-loop systems, chillers, and radiant heating setups. The solution is manufactured to high-purity standards, ensuring reliable performance in demanding environments where toxicity is a concern but food-grade certification is not required. It is compatible with standard piping materials, including copper, steel, and most plastics, ensuring seamless integration into existing infrastructure.

Key Properties

Chemical Component: Propylene Glycol (C₃H₈O₂) Solution
Concentration: 40% by volume
Appearance: Liquid
Specific Gravity: ~1.03 - 1.04
Corrosion Resistance: Contains industrial inhibitor package

Common Applications

HVAC & Chillers: Primary heat transfer fluid for industrial air conditioning and refrigeration units.
Closed-Loop Systems: Circulating fluid for hydronic heating and cooling loops.
Freeze Protection: Prevents bursting in pipes and systems exposed to low temperatures.
Process Cooling: Temperature regulation in manufacturing equipment and molding processes.
De-icing: Effective for industrial surface de-icing and snow melt systems.

Safety Precautions

Handle and store in a cool, dry area with adequate ventilation. While Propylene Glycol is low in toxicity, standard industrial hygiene practices should be followed. Wear appropriate PPE, such as gloves and safety goggles, to prevent skin and eye irritation. Use compatible storage materials like HDPE or stainless steel.

In the event of a spill, contain with inert absorbents and dispose of in accordance with local regulations. Refer to the Safety Data Sheet (SDS) for detailed handling instructions and emergency procedures.

Benefits

Corrosion Protection – Inhibitor package extends the life of pumps, pipes, and heat exchangers.

Ready-to-Use – Pre-mixed 40% solution eliminates the need for on-site dilution and water quality testing.

Low Toxicity – Safer alternative to ethylene glycol for systems with potential environmental exposure.
