PVA resin is a kind of heavy polymer. It is white or light yellow cotton-like, 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 …
PVA can be made from large particles into fine powder with different grade particle sizes by cryogenically crushing process, which can greatly accelerate the dissolution rate of PVA. For partial alcoholysis PVA powder, it can also be quickly dissolved in cold water. Application Widely used in various dry powder rubber powder, dry powder …

In the area of textile, PVA is primarily used as raw material of vinylon fiber and warp sizingagent. When PVA is used as raw material of vinylon fiber, it imparts the fiber with properties such aswhiteness, high strength, excellent hygroscopicity, and superior resistance to abrasion, sunlightand corrosion. Meanwhile PVA fiber can be spun in pure …
PVA has found wide use in the treatment of paper surface thanks to its excellent adhesivenessand dispersibility, and will not affect the performance of other binders used in combination. Paper treated by PVA can significantly enhance its toughness, surface strength (printability) Z-axis strength (internal strength), folding resistance, abrasive resistance, smoothness, glossiness, and resistance to oil …
