Polyvinyl alcohol are widely used in construction, coatings, adhesives, safety glass interlayers and other fields.
Building Grade Pva Powder For Adhesive
A. The aqueous solution of polyvinyl alcohol has strong adhesion to materials containing cellulose (such as paper, cloth, wood, etc.), and has the advantages of safety and non-toxicity. It can be used for laminating cardboard, bonding corrugated cardboard and office glue. Kraft paper bags for packing heavy objects such as cement, fertilizer and grain also use PVA as adhesive.
B. polyvinyl alcohol aqueous solution (by adding appropriate fillers and additives) is also widely used to prepare adhesives for printing and binding, paper tubes, cartons and other paper products.
C. under the action of acid catalysis, polyvinyl alcohol is condensed with formaldehyde, butyraldehyde, glyoxal or other aldehydes to generate polyvinyl acetals (such as PVAF and PVB) with stronger water resistance, adhesion and mechanical strength, which are widely used in construction, coatings, adhesives, safety glass interlayers and other fields.

Product Application
The aqueous solution of polyvinyl alcohol resin (PVA) has good film-forming and emulsifying properties. It can be used as a protective colloid for polymer emulsification and suspension polymerization. Polyvinyl alcohol can be used in textile pulp, Winnie fiber, coating agent for papermaking, building materials, adhesives, PVA films, PVB raw materials, food and medicine, etc. PVA can also be used as soil improver, polymerization suspending agent, emulsifier, quenching agent, etc. In addition, with the continuous development and improvement of PVA's performance, its application is still expanding.
