PVA BP 17 & PVA BF 17
LIWEI CHEMICAL CO. LTD
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.
The PVA production facilities of our company have been perfecting day by day with the long-term absorption and technological transformation on the basis of importing the complete set of technology from European Company. PVA produced by our company is good in performances and stable in quality. It enjoys a great reputation both at home and abroad. Liwei PVA 1788 can replace PVA BP17, Liwei PVA 1799 can replace PVA BF17.
