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.
