Ethylene Glycol 50/50

Product Overview

Ethylene Glycol 50/50 is a balanced aqueous solution containing ethylene glycol and water designed for reliable temperature control in industrial and automotive settings. The formulation combines thermal stability with a low freezing point, enabling efficient antifreeze performance and consistent heat transfer. This 50/50 mixture provides predictable rheology and pumpability across a wide range of operating conditions, making it suitable for closed-loop cooling systems, chiller circuits, and process heat exchangers. The product is manufactured to meet Technical Grade specifications, ensuring compatibility with metal components and typical coolants used in manufacturing facilities.

As a versatile coolant and heat transfer fluid, Ethylene Glycol 50/50 demonstrates excellent miscibility with water and common alcohols, and it maintains viscosity characteristics suitable for standard pumping systems. The solution supports reliable performance in aerospace de-icing contexts and general de-icing tasks where low-temperature operation is critical. The product’s quality is validated by multiple analytical tests, including GC/HPLC assay confirmation and rigorous impurity controls, aligning with industry expectations for industrial antifreeze applications.
