Antifreeze Glycol

What is antifreeze?

Almost all forms of coolants and heat transfer fluids rely on a glycol antifreeze to lower the freezing point of the solution. Common nomenclature calls the resulting solution antifreeze as well. Technically, though, it is more appropriate to call these solutions engine coolants or heat transfer fluids.

What are the types of glycols used for antifreeze?
There are two varieties of glycol: ethylene glycol and propylene glycol. Both can be used in automotive or heavy-duty engine coolants or glycol-based heat transfer fluids. Modern engines use a mixture of glycol and water for coolant, with corrosion inhibitor chemicals and dyes included with the glycol.

Which is the safer glycol for me to use for antifreeze?
Ethylene glycol is more toxic than propylene glycol. Ingesting a small amount of ethylene glycol is far more dangerous for small children or animals, for example, than ingesting a small amount of propylene glycol. Take appropriate steps to prevent the ingestion of either ethylene or propylene glycol, as well as new or used engine coolants containing these glycols.

Is it true that propylene glycol based antifreeze is environmentally friendly, compared to ethylene glycol based antifreeze?
Both propylene glycol and ethylene glycol have similar biodegradability and will eventually break down into nontoxic byproducts. Neither should be dumped in the environment. Antifreeze picks up heavy metals such as lead during use in the engine. Therefore, both ethylene glycol and propylene glycol antifreezes should be returned to a recycling center to minimize harmful effects on our environment after use. Spills should be cleaned up immediately.

Can your antifreeze protect against corrosion while being safe to use?
Our formulation has demonstrated outstanding performance in tests that measure its ability to prevent corrosion in all cooling system metals including aluminum, copper, cast iron, steel, and solder. SIERRA Antifreeze has shown excellent performance in all aspects of the ASTM D 5216 specification (Propylene Glycol Base Engine Coolant) and in the Ford BL2-2 Dynamometer Test.

Can I add propylene glycol based antifreeze to my existing ethylene glycol based antifreeze?
Ethylene glycol and propylene glycol are chemically very similar and can be mixed without harming the cooling system. Ethylene glycol does have better heat transfer properties than propylene glycol. Adding propylene glycol does not make the ethylene glycol less toxic.

Where can I buy antifreeze glycol?
You can buy online here at Antifreeze Glycols of ChemWorld. Our  stocks are  manufactured to US FDA standards. All products featured on site are in stock and ready to be shipped within 24 hours.
