Wei Connaught Chemical, Qingdao chemical gas manufacturers, ethylene glycol prices, glycol provided by Wei Connaught Chemical. We are Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) at: Qingdao, Shandong specialized in: phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol GB polyester level glycol liquid with a sweet taste and can be mixed with water in any proportion. The solvent used as starting materials, antifreeze, and synthetic polyester resins and the like. Cellophane may also be used for fibers, leather, adhesives, wetting agents. Production of synthetic resin PET, namely polyester fiber grade PET fiber, bottle-grade PET used to make mineral water bottles. Recently, the domestic chemical industry, ethylene glycol market prices are rising, according to Chinese paint procurement network is understood that the domestic market ethylene glycol plant in just three months, there have been six times rise, in addition, two Glycol is also emerging markets offer new high States since the 1950s, almost all using ethylene glycol as antifreeze. Ethylene glycol is a colorless, transparent, slightly sweet and viscous liquid having a hygroscopicity value of ethylene glycol, it is compatible with water in any proportion. The concentration of ethylene glycol is not the same. Freezing point is also different. Ethylene glycol - the freezing point of water with glycol antifreeze is not a linear relationship between the mass fraction. It is the freezing point of the aqueous solution is not completely reduced with the increase of the concentration, when the concentration exceeds 70%, but increased freezing. In the preparation process, from reality to be a reasonable choice to achieve frost resistance and economy requirements. Manufacturers in China Jiangnan glycol, commonly used glycol mass fraction of 40% ratio, while in the cold north, need to take the mass fraction of about 50% ethylene glycol ratio is more appropriate.
