Product introduction: 

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.

 Specifications：

Main features ：

Pva resin is a kind of heavy polymerization chemicals with no toxicity,no flavor and no contamination.it is white or pale yellow floccument,flake or powder in appearance.our pva is made by calcium carbide-acetylene method.PVA has good characteristic,such as thermal stability,water solubility,film formation.

Pva can dissolve together with other materials,such as starch,gum,synthetic resin,cellulose series,etc and the solution keep good stability.

Pva resin and pva film is resistant to oil,lubricant,organic solvent.PH value for pva solution is 

5-7 at room temperature. the viscosity is stable and don’t be affected by weak acid,weak base or organic solvent.

Pva owns the chemical properities of esterization,etherification and acetalation for long chain alcohol.

Application :

Textile Industry like warp sizing agent;Resin Finishing Agent;Adhensive for Screen PrintingPaper industry;Plywood and woodwork industries..Fiber procession;Textile sizing;AdhesionConstruction paint;stabilizer;Butyral resin production

Polyvinyl alcohol, organic compound, white flake, solid flocculent or powder, odorless.Soluble in water (above 95 ℃), insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc.Slightly soluble in dimethyl sulfoxide.Polyvinyl alcohol is an important chemical raw materials, used in the manufacture of polyvinyl acetal, resistant to gasoline pipe and vinylon synthetic fiber and fabric treatment agent, emulsifier, paper coating, adhesive, glue, etc.Polyvinyl alcohol resin series products can be dissolved in under 95 ℃ hot water, but due to the different polymerization degree and alcoholysis degree of high and low, alcoholysis method etc have certain differences in dissolution time, temperature, therefore in the use of different brand of polyvinyl alcohol resin, dissolved and time needs to be explored.When dissolved, stirring handing the goods slowly add the cold water of about 20 ℃ swelling, dispersion, and the transgression of volatile materials (do not directly into the product in more than 40 ℃ water to dissolve, to avoid package and skin to dissolve the endogenous phenomenon), and then heat up to about 95 ℃ dissolve faster, and insulation 2 ~ 2.5 hours, until the solution is no longer contains small particles, after 28 mesh, stainless steel filter impurities can be set aside.
