PVA is a water-soluble thermoplastic polymer prepared by partial or complete hydrolysis of PVAc with methanol or water. The chemical structure is: PVA is an odorless white flake, flocculent or powdery solid.
Although polyvinyl alcohol is often referred to by the acronym PVA, more generally PVA refers to polyvinyl acetate, which is commonly used as a wood adhesive and sealer.
Polyvinyl alcohol (PVA)-based hydrogels have attracted significant attention due to their excellent biocompatibility, tunable mechanical properties, and ability to form stable three-dimensional networks.
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.
PVA is used in the pharmaceutical industry as the coating on tablets and is an ingredient in laundry detergent sheets and pods and dishwasher detergent pods. According to laundry sheets maker...
