1、 Definition and purpose
Polyvinyl alcohol, or Pva, is an odorless, white flake, flocculent or powdery solid organic compound with the chemical formula of [c2h4o]n. PVA can be used to manufacture polyvinyl acetal, gasoline resistant pipes and vinylon, fabric treatment agent, emulsifier, paper coating, adhesive, glue, etc. it is an important chemical raw material. At the same time, PVA can also be used to develop new pharmaceutical excipients. Because PVA has the characteristics of convenient synthesis, safety and low toxicity, easy product quality control, low price and convenient use, PVA is an excellent pharmaceutical excipient with redevelopment potential.
