Polyvinyl Alcohol PVA powder, granule, flakes
1. Product Performance: Polymer is a kind of high polymer. It is white or light yellow floc, Granular or powdery in appearance. Its molecular formula is[CH2CHOH]n, and the molecular formula for some of the PVA is -[CH2CHOH]n-[CH2CHOOCCH3]m-. PVA is non-toxic, insipid and harmless. PVA is water-soluble and the solvent provide good viscosity and film building. It can withstand oils, lubricants, hydrocarbons and most other organic solvents. PVA has better chemical stability and insulatibility, and provide ease in firm building; It possess the typical chemical properties of polyols and can carry out process of esterification, etherealization, aceatalization etc.
2. Type: PVA 1788 PVA 1799 PVA 2488 PVA 2499 etc. ( flakes, powder, flocculent form)
Application:
1. Adhesive and thickener material in latex paints, paper coatings, hairsprays, shampoos and glues.
2. Textile agent
3. Barrier in (PET) bottles.
4. For use as synthetic vessels in flow testing.
5. Movie and children's play or slime when combined with.
6. Feminine hygiene and adult incontinence products as a plastic backing sheet.
7. As a because materials such as do not stick to it.
8. As a water-soluble film useful for packaging.
9. As fiber reinforcement in concrete
10. As a surfactant for the formation of polymer encapsulated nanobeads
