PVA film is a water-soluble film made from polyvinyl alcohol.
It is available in a wide range of types, from those that are soluble in cold water to those that are soluble in hot water, to respond to diverse needs.

Polyvinyl alcohol is an excellent water-based adhesive. The general product is flake, granular or flocculent. It is not easily� soluble in cold water. Heating is generally required during dissolution. After being finely pulverized and surface treated, it has� better cold water dissolving performance. But because of its thermoplasticity, pulverization becomes particularly difficult. Our� factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is� uniform. So that the material has excellent water solubility.

Product Description
ZHUOJUN® polyvinyl alcohol powder, also known as ZHUOJUN® PVA, is slightly off-white to beige stable non-toxic water-soluble macro-molecular synthetic polymer, which is made from vinyl acetate through the polymerization and saponification and quickly dissolves in water to form a stable colloid. It exhibits excellent water solubility, bonding strength, film forming properties and chemical stability.

Typical Applications:
- various construction mortar
- dry render / putty
- tile adhesives
- gypsum spray plaster binder

ZHUOJUN® PVA Advantages:
-Improves bonding strength
-Improves smoothness and surface gloss
-Improves oil resistance and abrasion resistance
-Improve film forming properties and chemical stability

Polyvinyl alcohol has excellent film forming, , and properties. It is also resistant to oil, grease and . It is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on , in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and is a quick dissolver. PVA has a melting point of 230°C and 180190°C for the fully hydrolysed and partially hydrolysed grades. It decomposes rapidly above 200°C as it can undergo at high temperatures.

PVA is an material but exhibits as the groups are small enough to fit into the lattice without disrupting it.

Uses:Preparation of is the largest use for polyvinyl alcohol in the U.S. and western Europe. Its use as a polymerization aid is the largest market in China. In Japan the major use is vinylon fiber production.

Some other uses of polyvinyl alcohol include:

Adhesive and thickener material in latex paints, paper coatings, hairsprays, shampoos and glues.

Textile agent

barrier in (PET) bottles.

for use as synthetic vessels in flow testing.

Movie and children's play or slime when combined with .

Feminine hygiene and adult incontinence products as a plastic backing sheet.

As a because materials such as do not stick to it.

As a water-soluble film useful for packaging.

As fiber reinforcement in concrete

As a surfactant for the formation of polymer encapsulated nanobeads

Used with polyvinyl acetate to make Elmer's glue

Used in eye drops and hard solution as a lubricant.

Used in protective chemical-resistant gloves

Used as a for specimen collection, especially stool samples

When doped with iodine, PVA can be used to polarize light.

As an agent in medical procedures

Property:
Pva is a very versatile water-soluble polymer, performance is between plastic and rubber, appearance is white powder.Water is a good solvent pva.Pva has good membranous, to form the film with excellent, frictional resistance, stretching intensity, and oxygen insulated.Because pva with two functional groups of hydrophilic group and hydrophobic group, therefore has the interfacial activity, so the pva can be used as a polymer emulsion and suspension polymerization reaction of protective colloid.
