Polyvinyl Alcohol(PVA)

Model Number

17-99,17-88,05-99,BP20,BP17,BP24

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 17-99(L) is chiefly used to produce textile sizing materials, coatings, adhesive and it is widely used for paper processing, emulsifying agents, dispersants and blocking colloids. Besides, it can be employed as membranes, soil modifiers, etc.
PVA 17-99(H) is mainly used to produce textile sizing materials, coatings, adhesive, acetal derivations, and it is extensively applied to paper processings, emulgents, dispersants and blocking colloids. In addition, it can be used as membranes, soil modifiers and production materials of vinylon fiber.
PVA 17-88 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 (12.5+-0.2)kg or (25+-0.3)kg each bag, and that of flaky PVA is (20.0+-0.3)kg each bag.
