Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH₂CH(OH)]_n. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in PVAc adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water. Without an externally added crosslinking agent, PVA solution can be gelled through repeated freezing-thawing, yielding highly strong, ultrapure, biocompatible hydrogels which have been used for a variety of applications such as vascular stents, cartilages, contact lenses, etc..

PVA is used in a variety of medical applications because of its biocompatibility, low tendency for protein adhesion, and low toxicity. Specific uses include cartilage replacements, contact lenses, and eye drops.Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest application in China is its use as a protective colloid to make polyvinyl acetate dispersions. In Japan its major use is the production of Vinylon fiber.This fiber is also manufactured in North Korea for self-sufficiency reasons, because no oil is required to produce it. Another application is photographic film.

PVA-based polymers are used widely in additive manufacturing. For example, 3D printed oral dosage forms demonstrate great potential in the pharmaceutical industry. It is possible to create drug-loaded tablets with modified drug-release characteristics where PVA is used as a binder substance.

Polyvinyl alcohol (PVA) resin is a high molecular polymer with a chemical formula of (CH2CHOH)n. It is a commonly used adhesive with good film forming properties, bonding properties and thermal stability. Its water solubility is related to the degree of alcoholysis. When the degree of alcoholysis is below 88%, polyvinyl alcohol can be dissolved in normal temperature water; when the degree of alcoholysis reaches 97%, hot water of 60-80 degrees C should be required for dissolution.

1, Polyvinyl alcohol can be applied in a variety of wall putty, drymix mortar, gypsum products, tile adhesive. It can effectively increase the adhesion of cement, ash calcium powder and gypsum. It can increase fluidity and slow the surface drying time to prevent product surface from cracking. It is suitable for wall/ceiling finishes and tile pastes.

2, adding 1-2KG of Polyvinyl alcohol with fineness above 300 meshes, into the latex paint production process, can effectively improve the smoothness of the product, improve the film formation and reduce the amount of emulsion used 5-10KG.

3, in the thermal insulation mortar system, 1 KG of Polyvinyl alcohol (160 mesh) has the similar effect of 4-5KG latex powder. In practical application, combine latex powder and Polyvinyl alcohol to use will achieve a better effect.

Polyvinyl alcohol (PVA) have a wide range of uses.
In the textile industry, it is used as warp slurry, textile finishing agent, and adhesives of non-woven fabrics.
In the construction industry, it is used as cement additives, molding plate adhesives, and building glues.
In the chemical industry, it is used semulsion stabilizer and dispersants.
In the papermaking industry, it is used as adhesives.
In addtion, It can be used in cosmetics industry, agriculture, pharmaceutical industry, etc.

Polyvinyl alchohol is an excellent water -based adhesive.The general product is flake , granular or flocculent .it is not easily soluble in cold water. Heating is gernerally required during dissolution. After being finely  pulverized and surface treated,it has better cold water dissolving performance.Our factory adopts a special liquid nitrogen low temperature cooling process to ensure that the flake of the crashed material is uniform.So that the material has excellent solubility.

PVA can be used in powder building materials , after stirring and mixing evenly, it could be use. Addition of advice: 0.3-3%of the total putty powder.
KP series use 100-120mesh when product dry glue powder, below 100 mesh it dissolves slow, difficult completely dissolve, when over 120 mesh, it is easy to agglomerate. Dry-mixed mortar use 80-120mesh. Powder putty use above 120 mesh, because below 120 mesh it is difficult to dissolve and make the surface unsmooth.
