Product Overview

30% Propylene Glycol Inhibited is a premium heat transfer fluid and antifreeze solution formulated with a specific package of corrosion inhibitors. Also known as Propane-1,2-diol (PG), this solution is pre-mixed to 30% concentration, offering immediate utility in industrial thermal applications without the need for on-site dilution. The inhibited formula stabilizes pH and creates a protective passivation layer on metal surfaces, significantly reducing corrosion rates in steel, copper, brass, and other alloys found in piping systems.

Engineered for reliability, this fluid provides excellent thermal stability and low viscosity, ensuring efficient pumping in closed-loop systems. It is widely used in HVAC chillers, solar thermal systems, and process cooling loops where freeze protection and equipment longevity are critical. While it meets USP-NF monograph standards for purity, the primary function of this inhibited blend is to maintain system integrity by minimizing cavitation, scaling, and oxidation.

Solar Thermal: Heat transport medium in solar water heating systems, capable of withstanding high stagnation temperatures.
Process Cooling: Coolant for plastic molding, brewing equipment, and general manufacturing machinery.

Safety Precautions

Store in a cool, dry area away from direct sunlight. Ensure storage containers are compatible with polyethylene or stainless steel. While Propylene Glycol is generally considered low-toxicity, standard industrial hygiene practices should be observed. Wear appropriate Personal Protective Equipment (PPE), including gloves and eye protection, during handling to prevent skin or eye irritation. Avoid contact with strong oxidizing agents. In the event of a spill, contain with non-combustible absorbent material and dispose of in accordance with local regulations. Refer to the Safety Data Sheet (SDS) for detailed safety, first aid, and disposal instructions.
