Polyvinyl Alcohol ( referred to as PVA)
white powder, is a wide range of uses of the water-soluble polymers,
performance between the plastic and rubber, its use can be divided into two
major fiber and non-fiber applications.
PVA has a unique strength in adhesion, film
flexibility, smoothness, oil resistance, solvent resistance, protective colloid
property, gas block, and abrasion resistance as well as having a specially
treated water resistance. Therefore, in addition to fiber materials for
outside, is also used extensively for the production of coatings, adhesives,
paper processing agent, emulsifier, dispersant, film and other products. Range
of applications throughout the textile, food, medicine, construction, wood
processing, paper making, printing, agriculture, steel, polymer and chemical
industries.
Performance: Polyvinyl Alcohol Resin products is white solid, good points flocculent, granular, powdery three kinds.
It is non-toxic, tasteless, non-polluting, can be dissolved in water 80--90 ℃. Its aqueous solution has good
adhesion and film-forming properties; resistance to most organic solvents oils,
hydrocarbons, lubricants and the like; polyhydric alcohols with long -chain
esterification, etherification, acetalization and other chemical properties.
Usage: Polyvinyl Alcohol PVA is mainly used
in the textile industry warp pulp , textile finishing agents, Polyvinyl Alcohol
fiber materials. 107 plastic construction and decoration industries, interior
and exterior paints, adhesives. In chemical industry as a polymeric emulsifier,
dispersant and polyvinyl formal, acetal, butyral resin. In Paper and paper
industry as a binder. In Agriculture for soil amendments, pesticides and
polyvinyl alcohol film adhesion synergist. Also can be used for cosmetics and
induction hardening agent aspects.
The way to test whether this product
completely dissolved: Take out a small amount of solution, add 1 ~ 2 drops of
iodine solution, if there is a blue granular white body, that has not been
completely dissolved, such as color can be evenly spread, has completely
dissolved.
