Ethylene Glycol

About Ethylene Glycol

Buy ethylene glycol (CAS 107-21-1) in pre-mixed and concentrated formulations from Alliance Chemical. Available in 50/50, 60/40, and 100% inhibited concentrations, plus semiconductor-grade purity for electronics manufacturing. Sizes range from quarts to 330-gallon IBC totes.

Products In This Collection

This collection includes ethylene glycol 50/50 pre-mixed (Laboratory Grade), 100% ethylene glycol inhibited (Laboratory Grade), ethylene glycol 60/40 (Technical Grade), and ethylene glycol semiconductor grade (99.5% minimum assay, typical 99.8%). The inhibited formulations include corrosion-inhibitor packages for closed-loop cooling, chillers, and boilers. The semiconductor grade features exceptionally low trace metal levels.

Common Applications

Ethylene glycol 50/50 is the standard pre-mixed coolant and antifreeze for HVAC systems, closed-loop chiller circuits, and industrial heat exchangers, providing freeze protection to approximately −37°C. The 60/40 ratio offers extended freeze protection to −51°C for extreme cold environments. 100% inhibited ethylene glycol allows custom dilution ratios. Semiconductor-grade ethylene glycol serves precision cooling in cleanroom environments, electronics manufacturing, and data center liquid cooling systems where trace metal contamination must be below 0.5 ppm.

Why Buy From Alliance Chemical

Every ethylene glycol product ships with a Safety Data Sheet (SDS) and Certificate of Analysis (COA). Alliance Chemical offers same-day shipping on in-stock items with no minimum order, from single-quart bottles to full IBC totes.

Frequently Asked Questions

What is ethylene glycol and what is it used for?

Ethylene glycol is an organic compound primarily used as an antifreeze and coolant in automotive and HVAC systems due to its ability to lower the freezing point of water and raise its boiling point. It's also a key ingredient in the production of polyester fibers, PET plastics, and is used in some de-icing applications. Alliance Chemical supplies ethylene glycol in various grades to suit diverse industrial needs.

What are the different grades of ethylene glycol available?

Ethylene glycol is available in several grades, including industrial grade, automotive grade, and semiconductor grade. The semiconductor grade is the purest, essential for applications where impurities can interfere with performance. Alliance Chemical provides different grades to match your specific purity and application requirements, complete with Certificates of Analysis.

How should ethylene glycol be stored safely?

Ethylene glycol should be stored in tightly closed, properly labeled containers in a cool, dry, and well-ventilated area, away from incompatible materials like strong oxidizers and acids. Keep it out of direct sunlight and away from sources of ignition. Always refer to the Safety Data Sheet (SDS) provided by Alliance Chemical for detailed storage and handling information.

Is ethylene glycol toxic?

Yes, ethylene glycol is toxic if ingested, inhaled, or absorbed through the skin. Exposure can cause serious health problems, including kidney damage and even death. When handling ethylene glycol, always wear appropriate personal protective equipment (PPE), such as gloves, eye protection, and a respirator if ventilation is inadequate. Refer to the SDS from Alliance Chemical for comprehensive safety precautions.

How do I dilute ethylene glycol for antifreeze applications?

The proper dilution of ethylene glycol for antifreeze depends on the desired freeze protection level. Typically, a 50/50 mixture of ethylene glycol and water provides protection down to -34°F (-36.7°C). Use distilled or deionized water to prevent mineral buildup. Alliance Chemical offers premixed 50/50 ethylene glycol solutions for your convenience.

What is the difference between ethylene glycol and propylene glycol?

While both ethylene glycol and propylene glycol are used as antifreeze and coolants, propylene glycol is considered less toxic than ethylene glycol. Propylene glycol is often preferred in applications where incidental human or animal contact is possible, such as in food processing or residential HVAC systems. Ethylene glycol is typically used in applications that prioritize performance and efficiency over toxicity.

What are the common concentrations of ethylene glycol products?

Ethylene glycol products are available in various concentrations, including pure (100%) and premixed solutions (e.g., 50/50). Pure ethylene glycol allows for custom dilution based on specific needs, while premixed solutions offer convenience and consistent performance. Alliance Chemical offers a range of ethylene glycol concentrations to suit different applications.

How can ethylene glycol be used in data center cooling?

In data centers, ethylene glycol is used in closed-loop cooling systems to remove heat from servers and other equipment. Its high heat capacity and ability to lower the freezing point of water make it an effective coolant, preventing equipment overheating and ensuring optimal performance. Alliance Chemical provides high-purity ethylene glycol suitable for the demanding cooling requirements of data centers. Inhibitors are often added to the glycol to protect metals in the system from corrosion.

What safety measures should I take when handling ethylene glycol?

Always wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and a respirator if necessary. Work in a well-ventilated area and avoid contact with skin, eyes, and clothing. In case of contact, immediately flush the affected area with plenty of water and seek medical attention. Refer to the SDS from Alliance Chemical for complete safety guidelines.

Does Alliance Chemical provide a Certificate of Analysis (COA) for ethylene glycol?

Yes, Alliance Chemical provides a Certificate of Analysis (COA) with each ethylene glycol product, detailing the chemical's purity, composition, and compliance with industry standards. This COA ensures that you receive a high-quality product that meets your specific application requirements, providing transparency and confidence in your purchase.
