Difference Between Polyethylene Glycol and Polyvinyl Alcohol

Polyethylene glycol is the polymerization of ethylene glycol into ether, the polymer unit is ether, polyvinyl alcohol is the copolymerization of vinyl bond, and the polymer unit is alcohol. The chemical formulas of the two substances are completely different, polyethylene glycol is H-[-OCH2-CH2-O]n-H; polyvinyl alcohol is [-CH2-CH(OH)-]n-


Polyethylene glycol is a high molecular polymer, the chemical formula is HO(CH2CH2O)nH, non-irritating, slightly bitter taste, good water solubility, and good compatibility with many organic components. It has excellent lubricity, moisture retention, dispersibility and adhesion, and can be used as antistatic agent and softener, etc. Processing and other industries have a wide range of applications.


And polyvinyl alcohol is a kind of water-soluble high polymer, its performance is between plastic and rubber, and it is widely used. In addition to being used as vinylon fiber, it is also widely used in the production of polyvinyl alcohol because polyvinyl alcohol is a water-soluble high polymer and a liquid substance, so it can be used as a liquid dispersant. Simply put, it has a moisturizing effect.
