Leaching - an overview | ScienceDirect Topics

Porogen leaching is one of the oldest polymer processing technologies to make porous products. The typical solvent casting–particle leaching (SC–PL) contains the selective leaching of an organic compound (glucose microspheres or gelatin) or of water soluble inorganic salts as KCl or NaCl (salt leaching), which are often used as porogens [53].
