Polyvinyl alcohol (PVA) powder series of products is specializedin construction industry as an additive in all kinds of dry powder putty, dry mortar, tile adhesive, especially used for building putty and Mortar, improving the flexibility, water retention and increase viscosity of mortar and putty. It’s adhesion very good and used to be widely with paper making, sizing material for textile, adhesive, film, and dry mortar field.
PVA Powder is the selection of high quality of PVA, and environment-friendly water soluble polymer.Ittakes liquid nitrogen as a medium, Crushing processing in low temperature environments, have a good at film forming property, emulsibility, cohesive property .the film it product has great force ,solvent resistance,abrasion resistance,tensile strength and oxygen denial property.Due to PVA have hydrophilic group and hydrophobic group,so PVA couble be protective colloid as Polymer emulsion
1,PVA 1788 is mainly used for the feedstock of vinylon fiber.The vinylon staple yarn and vinylon tow-to yarn manufactured from the PVA1788 exhibits white color,high strength,perfect hygroscpy,abrasion resistance,sunshine resistance and corrosion resistance.They can be blended with cotton,wool and glue fiber for weaving separately ,which is widely used for clothing ,tarpaulin ,tire cord ,fishingnets and ropes, and they are also an idea substitute of asbestos.
2,PVA1788 also can used in the field of paper manking,especially used as surface sizing.With good adhesion,good filming and strengthing to paper, PVA water solution can be used as surface sizing to substitute casein and starch which is more expensive and easy to be corrosible.The whiteness and gloss of the wove paper coated with PVA solution will be perfect,not easy to be crimped and with lower cost.Therefore,it is widely used in art paper ,craft paper,clothing paper and other high-grade paper.
3,It can also used as paper bonding ,vinyl acetate emusification &polymerization,inorganic binder , construction material additives,inorganic binder,cosmetic,medicine and temporary material additives etc.
