 Polyvinyl alcohol ( CHINA PVA )

Polyvinyl Alcohol is high polymer with excellent characters to dissolve easily in water but not to dissolve in common organic solvent and organic acids, and with excellent film-forming property,oil resistant, chemical-resistant. It can react with formaldehydes to form polyvinyl acetal.

In textile industry, PVOH is mainly used as a warp dressing agent, textile finishing agent
and the raw material of vinylon; in construction and upholstery industry 107 glue,
it's used as an additive of cement and mortar, inner and outer wall paints, and moulding
board binder;and in chemical industry,it's used as a polymer emulsifying agent,dispersing
agent and used to produce PVOH formal,PVOH acetal and PVOH butyral. It's used as an
adhesive in lumbering and paper-making industries, used as a soil improving agent,
pesticide reinforcing agent and PVOH thin film in agriculture, and used as a well-fixing
agent in petroleum exploitation. It can also be used into cosmetic, medicine, printing,
ceramics, steel-making, electronics and plating


 Partially hydrolyzed grades can be easily dissolve in cold water, so it should be cared that large and hard lumps are likely to
be formed when charging PVA into the water.
1.The water temperature should be lower than 25 when charging PVA.
2.The charging speed of PVA should be as slow as possible
3. After the charging, the slurry should be continuously stirred for about 10 - 15 minutes without     raising the temperature immediately, in order to disperse the particles efficiently.
4.The water temperature should be raised to about 95, to shorten the dissolving time. The lower  degree of polymerization is, the lower water temperature is acceptable for making solution.
