Schematic: Polyvinyl Alcohol (PVA) Production Process & Critical Control Points
  • Stage 1 – Polymerization of Vinyl Acetate Monomer (VAM): Conducted in batch reactors, with initiators and temperature control.
  • Stage 2 – Saponification: PVAc is reacted with methanol and sodium hydroxide, converting ester groups to hydroxyl – the degree of hydrolysis is precisely managed (typically 87–99.8%).
  • Stage 3 – Separation & Washing: PVA is filtered, purified by repeated washing, then dried under controlled temperature and humidity.
  • Stage 4 – Granulation and Packaging: Dried PVA is ground to custom mesh sizes, tested per ISO/ASTM standards, and packaged for distribution.
