Glycols & Glycol Ethers | Alliance Chemical

About Glycols and Glycol Ethers

Buy ethylene glycol, propylene glycol, and specialty glycol products from Alliance Chemical in Laboratory, Technical, and Semiconductor purity grades. Pre-mixed and concentrated formulations available in quarts through 330-gallon IBC totes.

Products In This Collection

This collection includes ethylene glycol 50/50 (CAS 107-21-1), 100% ethylene glycol inhibited, ethylene glycol semiconductor grade (99.5%+ assay), ethylene glycol 60/40, and 100% propylene glycol inhibited (CAS 57-55-6). Propylene glycol is often selected for food-processing support systems and closed-loop heat-transfer systems where lower toxicity is required.

Common Applications

Ethylene glycol formulations serve as the primary heat transfer fluid in closed-loop HVAC systems, industrial chillers, data center cooling systems, and automotive antifreeze applications. Propylene glycol inhibited is used in food processing facilities, breweries, and pharmaceutical plants. Semiconductor-grade ethylene glycol provides ultra-pure cooling for cleanroom equipment. Glycol-based coolants are also used in solar thermal systems, geothermal heat pumps, and hydronic heating and cooling.

Why Buy From Alliance Chemical

Every glycol product ships with a Safety Data Sheet (SDS) and Certificate of Analysis (COA). Alliance Chemical provides 1-2 business day shipping with no minimum orders, from bench-scale quarts to bulk IBC totes.

Frequently Asked Questions

What are the common applications of glycols and glycol ethers?

Glycols and glycol ethers are versatile chemicals used in applications such as antifreeze and coolant formulation, heat transfer fluid systems, deicing fluid production, and industrial solvent applications. Alliance Chemical supplies ethylene and propylene glycol formulations to meet these needs.

How do ethylene glycol and propylene glycol differ in terms of toxicity and safety?

Ethylene glycol is generally more toxic than propylene glycol. For safer applications, especially in environments with risk of human exposure, propylene glycol is often preferred. Alliance Chemical offers both options with the appropriate safety data to guide usage.

What concentrations of glycol are available from Alliance Chemical?

Alliance Chemical supplies both ethylene and propylene glycol in various concentrations, ranging from technical grade to high-purity specialty formulations. These options ensure compatibility with diverse industrial needs.

How should glycols and glycol ethers be stored safely?

Glycols and glycol ethers should be stored in tightly sealed containers in a cool, well-ventilated area. It's essential to keep them away from heat sources and oxidizing agents. Alliance Chemical provides detailed safety data sheets for more specific storage guidelines.

Can glycol be used in food processing applications?

Propylene glycol, in particular, is used in food processing as a humectant and preservative, where applicable. Always ensure the grade meets food-safe requirements. Alliance Chemical supplies suitable food-grade grades for relevant applications.

What safety precautions should be observed when handling glycol ethers?

When handling glycol ethers, it is important to avoid inhalation and skin contact by using appropriate personal protective equipment (PPE) such as gloves and masks. Refer to Alliance Chemical's safety data sheets for comprehensive safety instruction.

Which glycol type is preferable for HVAC systems and why?

For HVAC systems, ethylene glycol is often used, primarily for its efficient heat transfer properties, although propylene glycol may be chosen to avoid toxicity concerns in case of leaks into potable water. Alliance Chemical provides both types to meet system requirements.

What are common concentrations for glycol coolants?

Common concentrations for glycol coolants typically range between 30% to 70% mixed with water, depending on the desired freezing point and heat transfer efficiency. Alliance Chemical offers customized formulations to fit the specific parameters of cooling systems.
