Guangzhou Yang Qing Chemical Co., Ltd. Distribution of propylene glycol, glycerin, triethanolamine, AES, AOS, PEG series variety, reasonable prices. The company's main product, polyethylene glycol, can be divided into Dow DOW Polyethylene Glycol PEG-400 / PEG4000, Korea polyethylene glycol PEG400 / PEG600, Korea / Russian polyethylene glycol PEG6000, Malay Dow polyethylene glycol PEG600. Polyethylene glycol under normal conditions is very stable polyethylene glycol prices, but oxidation occurs at a temperature of 120 ℃ or higher temperature and oxygen in the air. Inert gas polyethylene glycol role, such as helium or carbon dioxide protection. Even polyethylene glycol is heated to 200 ~ 240 ℃ does not change. When the temperature rose to about 300 ℃, polyethylene glycol chain links will be broken and thermal cracking. Adding antioxidants such as 0.25 to 0.5% of phenothiazine, the chemical stability can be improved. Guangzhou Yang Qing Chemical Co., Ltd.
