The major use of ethylene glycol is as an antifreeze agent in the coolant in for example, automobiles and air-conditioning systems that either place the chiller or air handlers outside or must cool below the freezing temperature of water. In geothermal heating/cooling systems, ethylene glycol is the fluid that transports heat through the use of a geothermal heat pump. The ethylene glycol either ga… Webvapor density. 6.7 (vs air) Quality Level. 200. vapor pressure <0.01 mmHg . assay. 99%. mol wt. ...
