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.
Polyvinyl alcohol (PVA) resin is a polymer. Ití»s usually a white or slight yellow flocculent, flake, grnular or powdery solid. Its molecular formular is (C2H4O)n. Ití»s non-toxic, insipid, non-polluting. PVA is a water-soluble resin and has good chemical stability. It also has good adhesion, film-forming alibility, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols. And can make esterification, etherification, acetalation reactions.
PVA application

High tenacity and high modulus fiber is a kind of material mainly made by PVA. It is of high strength, high modulus, acidproof, alkaliproof, abrasion resistance and sunlight resistance, thus it is much better than the other products in general. With these excellent properties, it has a wide application in industry fabric, building reinforcing materials, package materials, ropes and meshes.
Water soluble PVA fiber is a particular kind fiber which can soluble in normal temperature, the solution temperature of this fiber are from 40~90 celsius degree, it is widely used in non-woven fabric, papermaking, spinning and weaving, medical treatment and health care etc. Especially, woven or non-woven fabrics made from it are used as embroidery linings, on which various lace designs can be embroidered, and after it is dissolved, all kinds of beautiful laces come into being. Besides ,it can extensively be used to produce sanitary sheets for women, baby napkins, medical and sanitary articles. in addition, it can also be used for vegetable seedings, planting crops and fruit trees to improve the output. this fiber can be used in textile to increase yarn count, level sizing and spin twistless yarn etc.

It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on humidity, 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. ZHUOJUN® PVA is fully degradable and is a quick dissolver.
