Application & Uses

PVA is used in sizing agents that give greater strength to textile yarns and make paper more resistant to oils and greases. It is also employed as a component of adhesives and emulsifiers, as a water-soluble protective film, and as a starting material for the preparation of other resins.

Application
- Paper sizing agent
- Warp sizing in textile
- Adhesive
- Raw material of polyvinyl alcohol panel and PVA thin film
- Paint and coatings
- Medicine, cosmetic and functional materials
- Emulgator and dispersing agent
  • Papermaking: PVA is used as a sizing and coating agent to make paper products stiffer. 
  • Textiles: PVA is used as a sizing and coating agent to make textiles stiffer. 
  • Medical applications: PVA is used in transdermal patches, jellies, tablets, and ophthalmic solutions. It's also used as scaffolding for cell cultures, embolic materials, contact lenses, and wound dressings. 
  • Water treatment: PVA is used in water treatment chemicals. 
  • Laundry detergents: PVA is used in laundry detergents. 
  • Agricultural chemicals: PVA is used in agricultural chemicals. 
  • Disinfectants: PVA is used in disinfectants. 
  • Industrial cleaning chemicals: PVA is used in industrial cleaning chemicals. 
  • Slime: PVA is used to make slime.

Dosage & Directions for Use

Is it safe for humans? Sub-chronic toxicity and genotoxicity studies confirm that PVA is safe for humans when exposed via numerous exposure pathways in typical daily exposure (1,2). However, the ingredients inside the PVA encasement are often not as safe.

Product Description & Chemical Profile

Polyvinyl alcohol (PVOH, PVA, or PVAl) is a synthetic polymer which is both colourless, odourless and water-soluble. It was initially discovered in the early 1920's and since has been used in numerous applications from the lamination of safety glass to the packaging of laundry detergents.
