PVA
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.
