 Polyvinyl alcohol ( CHINA PVA )

1. Polyvinyl alcohol PVA Performace 

Polyvinyl alcohol (abbreviated as PVA) also can be called PVOH. It is a kind of heavy polymer, produced by polymerization and alcoholysis of vinyl acetate.  PVA is white or light yellow floccus, granular or powdery in appearance.  Its molecular formula is[CH2CHOH]n,and the molecular formula for some of the PVA is -[CH2CHOH]n-[CH2CHOOCCH3]m-. PVA is non-toxic, insipid and harmless. It is water-soluble and the solvent provide good viscosity and film building.

 

2.Polyvinyl alcohol main use:

After PVA being treated by washing, wet-spinning, heating treatment, water-colling, oiling, it can obtain the fiber with good mechanical property.

PVA can be widely used for warp sizing and finishing .

Featured as anti-corrosion and anti-deterioration, stable quality etc, PVA aqueous solution has very strong adhesion force to cellulose (paper, cloth, wood).

PVA is widely used as architectural coating, such as for internal walls and floor.

Acetate, polyvinyl butyral and so on can be made by PVA reaction with formaldehyde, acetaldehyde, butyraldehyde.

PVA is also widely used for biodegradable film, protective colloid and soil amendments, seed and pharmaceutical coating agent, inorganic and electronic product adhesives, water-soluble film, cosmetic additive, temporary protective film and so on.
