  • Vinylon fiber is a synthetic fiber produced with PVA as a raw material, including vinylon staple fiber


  • Soluble PVA is soluble in water, the higher the water temperature, the greater the solubility, but it is almost insoluble in organic solvents.


  • PVA is the only vinyl polymer that can be used by bacteria as a carbon source and energy source.


  • Pharmaceutical grade polyvinyl alcohol, different from chemical grade polyvinyl alcohol, it is a very safe polymer organic substance, non-toxic to the human body, no side effects, and has good biocompatibility.


  • Polyvinyl alcohol is an important chemical raw material used in the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon, fabric treatment agents, emulsifiers, paper coatings, adhesives, glues, etc.


  • The production of polyvinyl alcohol is divided into three ways according to the different raw materials: one is petroleum → ethylene → vinyl acetate → polyvinyl alcohol; the second is natural gas → acetylene → vinyl acetate → polyvinyl alcohol; the third is calcium carbide → acetylene → vinyl acetate → Polyvinyl alcohol.
