WebOne of the simplest ways to prepare liposomes in a research laboratory is the thin-film hydration method followed by extrusion. This method involves making a thin lipid film in a round-bottom flask by the removal of organic solvent. Upon the addition and agitation of the dispersion medium, heterogeneous liposomes are formed. WebSolef® 11010 PVDF has been developed particularly to improve extrusion, blow molding, and rotomolding of low density polyethylene, high density polyethylene, and linear low density polyethylene as a processing aid. It is available in a free flowing powder form, is easy to handle and to dose accurately in masterbatch and/or polymer resins.
