Kuraray Poval™ – A champion in versatility
Kuraray Poval™
The applications of polyvinyl alcohols are wide-ranging: their main uses are in the paper, textile, emulsion, PVC, construc- tion, adhesives, packaging, and oil industries. As flexible, tear-resistant barrier films with a neutral taste, they keep food and other products fresh. In the paper industry they play an important role, as carriers for optical brighteners, in bar- rier coatings against mineral oils/fat, and in paper for inkjet printing. As a component used in the cementation of oil wells Kuraray Poval™ controls fluid loss and the setting time of mortar. It is also used as a temporary binder to facilitate the production of high-strength industrial ceramics. Its solvent resistance en- sures the functionality of protective clothing. Certain Kuraray Poval™ grades have unique properties for the polymerisation of suspension PVC and the manufacture of VAE emulsions. A high polyvinyl alcohol content in the pro- duction of sponges makes them resistant to chemicals and enhances their mechanical stability. The physical and chemi- cal properties of polyvinyl alcohols make them suitable for a wide range of applications. Kuraray Poval™ is water-soluble, has specific colloidal charac- teristics, excellent film-forming properties, and high tensile strength. In addition, it is elastic and resistant to heat and organic solvents. Above all, the range of applications is based on its chemical properties, especially on the ability of its numerous hydroxyl groups to react with substances such as reactant resins, alde- hydes and other reactive compounds.
