Crosslinked polyvinlypyrrolidone / Polyvinylpolypyrrolidon



1、Name of Product: Vinylpyrrolidone and vinyl acetate copolymer /Copovido

      CAS NO.:25249-54-1, 9003-39-8

2Overview of performance:

W hite or cream white, free-flowing powder, hygroscopic, odorless or with characteristic smell, insoluble in water, alkali, acid and all other common solvents, swells rapidly in water but without forming a gel.
To assure the effectiveness of the medicine, tablets and capsules are required to disintegrate within a certain time, if different adding methods of the disintegrating agent are used, the different disintegrating and dissolution speeds will be achieved. It is regarded as the top disintegrating agent thanks to its excellent swelling characteristics after the absorption of moisture.
