Both ethylene and propylene glycol possess many characteristics that make them ideal for use in heat transfer systems where protection from freezing is required. Desirable properties include high boiling points, low freezing points, stability over a wide range of temperatures, and high specific heats and thermal conductivities. Furthermore, used with an appropriate inhibitor, glycols demonstrate a non-corrosivity that may substantially prolong system life. Ethylene glycol based solutions work well in most anti-freeze applications because of their excellent heat transfer efficiency. The low viscosity of ethylene glycol allows systems to operate at lower minimum temperatures and is more energy efficient due to its reduced pumping requirements. The primary drawback to ethylene glycol is that it is listed as a "toxic chemical" under SARA, Title III, Section 313, due to its acute oral toxicity. Inhibited propylene glycol should be used for freeze protection where direct contact with foodstuffs or incidental contact with drinking water may occur. Although propylene glycol is generally recognized as safe (GRAS) by the FDA, it is not intended for human consumption. Hope this helps your question.

What ethnic group makes up 90 percent of the population of Chile?
The majority ethnic group in Chile is made up of people of mixed European and indigenous descent, known as Mestizos. They make up about 90% of the country's population.
What type of economy do most nations have?
Most nations have mixed economies, where both the government and the private sector play a role in economic decision-making. In these economies, elements of both capitalism and socialism are present.
What is the mixed number for ten sevenths?
The mixed number for ten sevenths is 1 3/7. This means there is 1 whole number and 3/7 left over.
What percent of South Africa is white?
During the "Apartheid" era until 1994, white South Africans owned approximately 80% of the country while only being 15-20% of the total population. South Africa is still today, the leading producer of food in Africa and is also the only country in Africa which can feed itself.
In 1787 approximately what percent of non Native American inhabitants of the thirteen states were of European ancestry?
In 1787, approximately 90-95% of the non-Native American inhabitants of the thirteen states were of European ancestry. Native Americans, African Americans, and individuals of mixed ancestry made up the remaining 5-10%.
What does ethylene glycol do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
Why Ethelyene Glycol is mixed with water in a radiator coolant?
Ethylene glycol is mixed with water in a radiator coolant because it has a lower freezing point and higher boiling point than water. This helps prevent the coolant from freezing in cold temperatures and boiling in hot temperatures, which can protect the engine from damage. Additionally, ethylene glycol also helps to prevent corrosion and lubricates the water pump.
Is glycol antifreeze?
Yes, glycol is commonly used as antifreeze. Ethylene glycol and propylene glycol are two types of glycol widely utilized in antifreeze formulations. They work by lowering the freezing point of the liquid in which they are mixed, preventing it from freezing under cold temperatures. This property makes glycol essential in automotive and industrial cooling systems to protect engines and machinery from freezing and overheating. Chemical Iran offers high-quality glycol products suitable for antifreeze applications. Their ethylene glycol and propylene glycol products are known for their purity and effectiveness in maintaining optimal operating temperatures. By providing reliable glycol solutions, Chemical Iran ensures that vehicles and equipment perform efficiently and safely in various temperature conditions.
Can propylene glycol antifreeze and ethylene glycol antifreeze be mixed?
Yes, Ethylene glycol and Propylene glycol are very similar chemically, therefore, can be mixed without any bad consequences for the engine.
What is antifreeze made of?
Gasline antifreeze is usually just isopropyl alcohol. Many drugstores sell 97-percent isopropanol, and if you put six ounces of it in a 20-gallon gas tank it will do the same thing as Heet (or whatever brand you like) for less money.
What does ethylene do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
What temperature does antifreeze solution freeze at on the Fahrenheit scale?
It would depend on the ratio of your antifreeze mix (typically glycol and water). If mixed 1:1 or 50/50, the solution will freeze at around -40°C (which can also be represented by -40°F) More glycol = a lower freezing point
What are two properties that make ethylene glycol an ideal antifreeze?
Well, when mixed in an ideal solution with water, it has a relatively high boiling point and low freezing point. Also, it doesn't cause rust/corrosion.
What 2 things does antifreeze change?
because.... 333246 is the answer NOT!! :)
Why does ethylene glycol and water mix in any ratio?
Ethylene glycol and water can be mixed in any ratio because of their compatibility and makeup. It is primarily used to prevent water from freezing and increase its boiling point for automobiles.
What is the mixed number for 150 percent?
The mixed number for 150 percent is 11/2
How do you turn a mixed number into percent?
you turn percents into mixed numbers by turning the percent into a fraction then a mixed number
