Advantage:
PEG is soluble in water, ethanol and many kinds of organic solvents, and stable to heat, acid and alkali. and don't react with a lot of chemicals, with good performance of hygroscopicity, bondability, lubricity, and is non-irritating and harmless to human and animal. PEG is a polyether polymer with widely usage, it can be used in numerous fields such as medicine, electronic, chemical, food, and so on.
