Ethylene Glycol 50/50

Product Overview

Ethylene Glycol 50/50 is a precision-blended aqueous solution containing Laboratory Grade ethylene glycol (Monoethylene Glycol or MEG) and water. Designed for immediate application in industrial and automotive thermal management systems, this pre-mixed formulation eliminates the need for on-site dilution and water quality testing.

The 50/50 ratio provides an optimal balance of thermal conductivity and freeze protection, making it a standard choice for closed-loop cooling systems, chiller circuits, and process heat exchangers. As a versatile heat transfer fluid, it maintains predictable rheology and pumpability across a wide operating temperature range. This product matches Technical Grade specifications, ensuring compatibility with standard industrial metals and elastomers used in manufacturing and cooling infrastructure.

Safety and Handling

Handle Ethylene Glycol 50/50 with care. Store in tightly closed containers (HDPE or stainless steel recommended) in a cool, dry area away from direct sunlight. Ensure proper ventilation during use. Wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles, to prevent skin and eye contact.

This product is chemically classified under CAS 107-21-1. While it offers excellent thermal properties, Ethylene Glycol is toxic if ingested. For applications where incidental food contact is possible, Propylene Glycol is the recommended alternative. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures, spill containment, and disposal regulations regarding UN 3082 environmentally hazardous substances.
