PVA is water-solube macromolecule compound, easy to be dissolved in water. Under the catalysis of hydrochloric acid it condenses with ormaldehyde and generates thermo-plastic macromolecule compound, available with excellent waterproof,durable and preservative performances. The coating is not to bulge and become fragile in contact with water. And it is cheap for the price and easy for construction, no toxicity and taste, which is used in a wide range in China as the construction coatings.
PVA has a very strong adhesion to cellulose( paper, cloth, wood), and has such characteristics as no deterioration and steady quality and can substitute starch, water glass or use together with them, hence, it is widely used as the adhesives of printing,binding and paper processing products and so on.
PVA is mainly used for the feedstock of vinylon fiber.The vinylon staple yarn and vinylon tow-to yarn manufactured from the Sundy Brand PVA exhibits white color, high strength, perfect hygroscopy, abrasion resistance, sunshine
resistance and corrosion resistance. They can be blended with cotton, wool and glue fiber for weaving or weaving separately,which is widely used for clothing, tarpaulin, tire cord, fishing nets and ropes, and they are also an ideal substitute of asbestos.
