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 rapid shipping on in-stock items with no minimum order, from single-quart bottles to full IBC totes.

Frequently Asked Questions

What are the typical applications for ethylene glycol?
Ethylene glycol is commonly used in automotive antifreeze, HVAC systems, polyester fiber manufacturing, and semiconductor cooling. Alliance Chemical offers a variety of grades tailored to these applications.
Which grades of ethylene glycol does Alliance Chemical offer?
Alliance Chemical provides ethylene glycol in various grades, including industrial and semiconductor-grade, to suit different applications such as heat transfer and electronic cooling.
What concentration of ethylene glycol should I use for automotive antifreeze?
For automotive antifreeze, a common concentration is a 50/50 mix of ethylene glycol to water, providing effective freeze protection. Alliance Chemical offers these pre-mixed solutions for convenience.
Is ethylene glycol safe to use in HVAC systems?
Yes, ethylene glycol is commonly used in HVAC systems for its efficient heat transfer properties. However, ensure proper handling and storage, as it should be kept in a cool, dry place away from contaminants.
How should ethylene glycol be stored?
Ethylene glycol should be stored in a clean, dry area away from direct sunlight and incompatible substances. Use containers that prevent leaks to maintain its quality and safety.
What safety precautions should be taken when handling ethylene glycol?
Wear appropriate protective gear, such as gloves and goggles, to prevent skin and eye contact. Ensure good ventilation and follow Alliance Chemical's safety data sheet guidelines for safe handling.
How does ethylene glycol work as a coolant?
Ethylene glycol acts as a coolant by reducing the freezing point and increasing the boiling point of water, making it ideal for heat transfer applications. It helps maintain optimal temperatures in various systems.
Can ethylene glycol be used for semiconductor cooling?
Yes, ethylene glycol is used in semiconductor cooling due to its effective thermal conductivity and low toxicity. Alliance Chemical offers semiconductor-grade ethylene glycol for this purpose.
What are the differences between industrial and semiconductor-grade ethylene glycol?
Industrial-grade ethylene glycol is suitable for general applications like antifreeze, while semiconductor-grade has higher purity levels required for sensitive electronics cooling. Alliance Chemical provides both options.
