Chemical Profile

Product Overview

30% Propylene Glycol Technical Grade is a clear, colorless aqueous solution composed of 30% propylene glycol (Propane-1,2-diol) and 70% deionized water. Designed for industrial applications, this pre-diluted formulation ensures consistent batch-to-batch performance without the need for on-site mixing. It serves as an effective heat transfer fluid, freeze point depressant, and industrial solvent.

While chemically similar to USP grades, this Technical Grade product is specifically cost-engineered for industrial systems where pharmaceutical purity is not required, such as closed-loop heating and cooling systems, industrial manufacturing, and textile processing. It offers excellent thermal stability and material compatibility.

Heat Transfer Fluid: Used in HVAC chillers and closed-loop heating systems to lower the freezing point of water and prevent burst damage.
Industrial Antifreeze: Provides freeze protection for industrial equipment and sprinkler systems in non-occupied spaces.
Paints and Coatings: Acts as a solvent and leveling agent in water-based architectural paints and industrial coatings to improve durability.
Chemical Intermediates: Utilized in the production of high-performance unsaturated polyester resins.
De-icing: Used in non-aviation de-icing applications for machinery and runways.

Safety Precautions

Store in a cool, dry, well-ventilated area away from direct sunlight and strong oxidizing agents. While Propylene Glycol is generally considered low-toxicity for industrial use, standard safety protocols should be observed. Wear appropriate Personal Protective Equipment (PPE), including safety glasses and gloves, during handling to prevent skin and eye irritation.

Ensure storage containers, such as HDPE or stainless steel, are tightly sealed. Refer to the Safety Data Sheet (SDS) for comprehensive handling, storage, and emergency response guidelines.
