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 …
PVA fine powder are specially designed for cement additives and contruction industry. They improve plaster properties such as flexibility, water retention, and increase plaster viscosity as well. In addition, they do not only reduce the friction of plaster but also enhance its working capacity and quality (Prevent cracking and shedding of plaster, increase adhesion and …

PVA can be used to produce water soluble film and water-resistant film. PVA film is widely used in textile, food, detergents & cosmetics, agricultural chemicals, and dyestuff areas owing to itsinherent features, namely, high tensile strength, resistance to organic solvent and air tightness. And also PVA is the material of polyvinyl butyral which is widely …
PVA can be widely used as protective colloid or thickener for the emulsion polymerizationof vinyl acetate (VAC) and acrylates for its following advantages: excellent adhesiveness, increased initial tack and drying rate while used with filler, superior resistance to oil, outstandingfilm strength and prolonged stability. Grade & Specification Product Grade Hydrolysis Viscosity Volatiles Ash pH …
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 …
