Physicochemical characterization of felodipine-kollidon VA64 amorphous solid dispersions prepared by hot-melt extrusion

, 2013
To improve the dissolution and hence the oral bioavailability, amorphous felodipine (FEL) solid dispersions (SDs) with Kollidon (R) VA 64 (PVP/VA) were prepared.

The die swell eliminating mechanism of hot air assisted 3D printing of GF/PP and its influence on the product performance

e-Polymers
For eliminating the die swell phenomenon in 3D printing of GF/PP, a hot air assisted 3D printing method is proposed and its mechanism is studied. A two-phase flow model consisting of compressible gas and in-compressible melt is established, and the ...
