One option is to buy a Refractometer tester to test the Propylene Glycol. While you might see propylene glycol described as an organic compound, this does not mean it’s naturally occurring. 4.4 … Propylene glycol and ethylene glycol are both used as antifreeze for cars and trucks They are chemically similar in many respects, with propylene glycol considered to be a safer alternative than its ethylene cousin; however, ethylene glycol has better heat transfer properties. When a reaction takes place between ethylene oxide with water, the ethylene glycol oligomers or the ethylene glycol, it gives rise to polyethylene glycol. There are also coolants made with ethylene glycol and propylene glycol, and each one has its own benefits and downsides. 99. It transfers heat better than propylene glycol, and can function at temperatures as low as -100º F. Ethylene Glycol is an excellent choice for protecting natural metals. June 17, 2015 Newsletter Dynalene. Looks like AMSOIL makes Propylene Glycol based coolant. Here it shows that the solution could be 30% Propylene Glycol. It's said to be less toxic and animal friendly. A propylene glycol base engine coolant is described which assists the heavy duty user in solving many current problems related to cooling This syrupy fluid isn’t as hazardous as ethylene glycol. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. Uses. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines. Ethylene glycol vs propylene glycol. Later, ethylene glycol was developed as the main antifreeze. The bad news is it is the red Walmart RV type (actually it's Camco brand), which uses denatured ethanol instead of propylene glycol. Due to environmental concerns, the main component of the coolant was replaced by ethylene glycol. Molar Mass The molar mass of ethylene glycol is 62 g/mol. There is a small percentage of propylene glycol based coolant on the market. This helped the coolant cope with high engine temperatures. Ethylene glycol and propylene glycol are the major constituents of antifreeze. Ethylene glycol is produced when a reaction takes place between the ethylene oxide and water. When a glycol-water mixture is altered, the freezing point of the coolant also changes. If you can find some, I would think that would help. Propylene anti-freeze is going to be much more expensive since that particular compound is used in many other applications. A major change in radiator gaskets in the 1950s led to the development of the radiator cap, which allowed pressurized coolant. 4.7 out of 5 stars 104. To extend this range, other chemicals like ethylene glycol and propylene glycol are added. Is anyone using Propylene Glycol based coolant here? Propylene Glycol is een cosmetische vorm van minerale olie en wordt ook wel genoemd als een goedkoper alternatief voor glycerine, dat bovendien sneller in de huid trekt. The reaction is catalyzed by acidic or basic catalysts. And where is the drain plug on the rad? Ethylene glycol and its oligomers are preferable as a starting material instead of water, because they allow the creation of polymers with a low polydispersity (narrow molecular weight distribution). A balanced inhibitor system, to protect common metals of construction. The ability of ethylene glycol and propylene glycol to lower the freezing point of water constitutes the most important physical property in coolant applications and the primary reason for using glycol-based heat transfer fluids.
