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
230C and 180190C for the fully hydrolysed and partially
hydrolysed grades. It decomposes rapidly above 200C 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:
1.Adhesive and thickener material in latex paints, paper
coatings, hairsprays, shampoos and glues.
2.Textile agent
3.barrier in (PET) bottles.
4.for use as synthetic vessels in flow testing.
5.Movie and children's play or slime when combined with .

9.As fiber reinforcement in concrete
10.As a surfactant for the formation of polymer encapsulated
nanobeads
11.Used with polyvinyl acetate to make Elmer's glue
12.Used in eye drops and hard solution as a lubricant.
13.Used in protective chemical-resistant gloves
14.Used as a for specimen collection, especially stool samples
15.When doped with iodine, PVA can be used to polarize light.
