Downstream polyester downturn, low operating load glycol, ethylene glycol market for the next tow influence increases. Countries since the 1950s, almost all using ethylene glycol as antifreeze. Ethylene glycol is a colorless, transparent, slightly sweet taste and hygroscopic viscous liquid, it is compatible with water in any proportion. The concentration of ethylene glycol is not the same. Freezing point is also different. Glycol - antifreeze freezing point of water with glycol mass fraction is not a linear relationship. Its freezing point aqueous solution is not entirely decreased with increasing concentration of ethylene action, when the concentration exceeds 70% ethylene industry, but increased freezing point. In the preparation process, from reality to be a reasonable choice to purchase ethylene glycol antifreeze and economy to meet the requirements. In southern China, the general mass fraction of 40% glycol ratio, while in the cold north, need to take the mass fraction of about 50% ethylene glycol ratio is more appropriate.
