PVP VA64 / PVP VA55 / PVP VA37 / PVP VA73
PVP-VA readily dissolves in all hydrophilic solvents.
Solutions of more than 10% concentration can be prepared in water, ethanol, isopropanol, methylene chloride, glycerol and propylene glycol It is less soluble in ether, cyclic, aliphatic and alicyclic hydrocarbons.
PVP / VA series products play the role of stiffener and film former; the higher proportion of vinyl acetate, low hygroscopicity, very suitable for mousse, hair spray and styling solution;
PVP / VA 64 series products are commonly used emulsifiers and protective colloids for plant protection agents;
Can be used for rewet type adhesives, paper adhesives
The main application is as soluble binder for granulation and as dry-binder in direct compression technology, as a film-forming agent in sprays and as pore-former in coating and taste-masking applications, as well as solubilizer in hot melt extrusion processes.
Especially suitable for direct compression, roller compaction, hot melt extrusion processes as well as for markets with high humidity exposure.
Superior plasticity for very hard tablet production.
Compliant with the current monographs for copovidone.
