In applications where toxicity is NOT a concern, ethylene glycol is often the heat transfer fluid of choice. When a reaction takes place between ethylene oxide with water, the ethylene glycol oligomers or the ethylene glycol, it gives rise to polyethylene glycol. The propylene glycol coolant does not decompose in the engine if the additive package is maintained. There is a small percentage of propylene glycol based coolant on the market. Here it shows that the solution could be 30% Propylene Glycol. Propylene glycol and ethylene glycol are widely used in the HVAC industry to protect systems from damage caused by freezing and corrosion. It's not totally safe however, and you should ensure that you don't have any coolant leaks. In our hypothetical example, if the grey and white shaded Glycols are normally used for industrial HVAC, Process cooling/heating, and antifreeze. For example, ethylene glycol is more efficient and works better under lower temperatures. 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. Freeze protection, as the graphs illustrate, show that maximum protection is achieved with Ethylene Glycol Coolants at 67% antifreeze and Propylene Glycol coolants at 100% antifreeze. Although propylene glycol … If you can find some, I would think that would help. Operating an automobile without proper antifreeze can cause permanent damage, so testing ethylene and propylene glycol is an important component of proper vehicle maintenance. My car shares the same garage with our two dogs. It is safer than ethylene glycol, and works just as well. Another option might be to drain the system and replace the coolant with Ethylene Glycol antifreeze. There are also coolants made with ethylene glycol and propylene glycol, and each one has its own benefits and downsides. $23.99 $ 23. Ethylene Glycol: Ethylene glycol is mainly used for the manufacturing of polyester fibers and as an automotive antifreeze. Ethylene or propylene glycol, to depress the freeze point of the fluid. Propylene glycol is less toxic than ethylene glycol and has perceived environmental benefits; however, these are off-set by higher cost.
