Ethylene glycol is a colorless, transparent, slightly sweet, and hygroscopic viscous liquid that can be mixed with any proportion of water. When the concentration of ethylene glycol is different. The freezing point is also different.
There is no linear relationship between the freezing point of ethylene glycol aqueous solution and the concentration of ethylene glycol. The freezing point of its aqueous solution did not completely decrease with increasing concentration. When the concentration exceeds 70%, the freezing point will actually increase.
In the preparation process, in order to meet the requirements of frost resistance and economy, reasonable choices should be made based on reality. In low latitude regions, the concentration of ethylene glycol is generally 40%, while in cold high latitude regions, the concentration of ethylene glycol is more appropriate at around 50%.
