an•ti•freeze (ˈæn tɪˌfriz, ˈæn ti-) n. a liquid, as ethylene glycol, used in the radiator of an internal-combustion engine to lower the freezing point of the cooling medium. [1910–15] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Lt...
Pure water freezes at 32° F. A mixture of 30% propylene glycol to 70% water has a freeze point of 8°F, but the burst point is -18°F. At this temperature the system will be protected, the coolant will become slushy but able to flow into expansion tank. This is very important fo...
A: If your system or atmosphere have the potential to go below 32°F (0°C), then a glycol-water mixture should be used. A chiller's process fluid should never freeze, as this stops the chiller's ability to do work, and could even cause mechanical damage.9...
With the Glycol Tester you will know the exact freeze protection temperature of the glycol solution in your ice rink refrigeration pipe grid system and be able to protect your rink system from freeze damage.
Glycol fluids provide excellent thermal properties for water-based HVAC or cooling systems by significantly reducing the freeze point of water. Without glycol, these systems would seize up & expand dramatically, leading to deformed pipes or burst connections. However, glycol chemistry can degrade over...
Properties like freezing point, viscosity, specific gravity and specific heat of ethylene glycol based heat-transfer fluids, or brines.

Ethylene glycolreaches a peak serum level 2 to 4 hours after ingestion. It is water soluble and has a Vdthat is equal to total body water (0.6 L/kg). It has a molecular weight of 62 g/mole.144Figure 51-2displays the metabolism ofethylene glycolto its products.Ethylene glycolis oxidized...
steam-set printing inks and wood stains. With a low vapor pressure and a high boiling point, its uses and properties are similar to those of ethylene glycol and diethylene glycol. Because it is an efficient hygroscopic agent it serves as a liquid desiccant for removing water from natural gas...
which is slightly lower than that of ethanol. Propylene glycol is commonly used as a plasticizer for aqueous film coating materials. The same amount of mixed liquid with water can delay the hydrolysis of some drugs and increase the stability of the preparation product. 15% ~ 30% propylene glyc...
