Details

The molecular weight of PVPK90 is about 600,000, and it belongs to the high K - value type among povidone series products.

• Product Name: PVP - K90 (Povidone K90)
• Chemical Name: 1 - Vinyl - 2 - pyrrolidone homopolymer
• CTFA Name: POLYVINYLPYRROLIDONE
• CAS No.: 9003 - 39 - 8
• Molecular Formula: (C?H?NO)?
• Chemical Structure
• 

• Physical Properties

  • Solubility and Solution Characteristics:

     

    The aqueous solution of PVPK90 is non - thixotropic in most cases and has a very short relaxation time. When the concentration is very high, it will have a certain structural viscosity; the viscosity will decrease when the shear force is increased. Controlling the concentration of PVPK90 will bring many different application properties to PVPK90.

  Applications

  • As the main component of adhesives, the most widely used in industry are solid glue sticks, pressure - sensitive adhesives and rewet adhesives, etc.
  • It can be used in the preparation and processing of many inorganic fibers such as carbon fibers, Al?O? fibers, and magnesium titanate fibers to increase the bonding force when the fibers are compounded with resins.
  • In ceramic processing, PVP can be completely burned during sintering. Therefore, it has no effect on the ceramic itself.
  • PVP K90 can also prevent ceramic products from cracking before sintering and can also eliminate the phenomenon of skinning on the surface of ceramic green bodies.
  • It can be used in the manufacture of various functional membrane materials to improve membrane selectivity, such as: kidney dialysis membranes.
