Description
Polyvinyl alcohol ( PVA) is a water-soluble synthetic polymer with
excellent film-forming, emulsifying, and adhesive properties. This
versatile polymer offers outstanding resistance to oil, grease and
solvents, plus high tensile strength, flexibility, and high oxygen
barrier.
Application:
PVA ****9(L) is chiefly used to produce textile sizing materials,
coatings, adhesive and it is widely used for paper processing,
emulsifying agents, dispersant and blocking colloids. Besides, it
can be employed as membranes, soil modifiers, etc.
PVA ****9(H) is mainly used to produce textile sizing materials,
coatings, adhesive, acetate derivations, and it is extensively
applied to paper processing, emulgents, dispersant and blocking
colloids. In addition, it can be used as membranes, soil modifiers
and production materials of vinylon fiber.
PVA ****8 is chiefly used for coatings, adhesive, dispersing
agents, emulgents, textile sizing materials, sensitize coatings and
so forth.
Package:
Packed with polypropylene woven bags. The net weight of flocculent
PVA weighs (*2.5**0.2)kg or (*5**0.3)kg each bag, and that of flaky
PVA is (*0.0**0.3)kg each bag.
