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… WebPolyethylene glycol Product Number P 5413 Store at Room Temperature Product Description General formula: H(OCH2CH2)nOH, average value of n = 181.4 Average Molecular Weight: 8,000 (7,000-9,000) CAS Number: 25322-68-3 Melting Point: 59 - 64 °C Density: 1.0845 g/ml (70 °C); 1.0689 g/ml (90 °C) Synonym: PEG, Carbowax, Macrogol
