Polyvinyl alcohol (PVOH, PVA, or PVAl) is a synthetic polymer which is both colourless, odourless and water-soluble. Polyvinyl alcohol (PVA), a colourless, water-soluble synthetic resin employed principally in the treating of textiles and paper. Water-soluble PVOH manufacturing is complex and requires considerable investment and technical expertise to produce resins that demonstrate the desired characteristics. However, in the last five years, there have been a substantial increase in new patent applications for PVOH resins and films.
Polyvinyl alcohol (PVA) Application:
Mainly used in fiber processing raw materials, butyral resin raw materials, textile pulp, paper surface sizing, pigment carrier, paper binder, architectural coating binder, building material binder, film, vinyl acetate Emulsion polymerization stabilizer, PVA rubber, etc.
Polyvinyl alcohol (PVA) Productivity: 160000MTS
