Abstract:
1. A method comprising: continuously introducing a matrix material into a mold cavity, wherein the matrix material comprises an active particle and a binder particle, and wherein the binder particles have a melt flow index of less than about 3.5 g/10 min at 190° C. and 15 kg according to ASTM D1238, a bulk density of about 0.1 to about 0.5 g/cm disposing a release wrapper as a liner of the mold cavity; heating at least a portion of the matrix material to about 175° C. to about 300° C., so as to bind the matrix material at a plurality of contact points thereby forming a porous mass length having an encapsulated pressure drop of about 10 mm of H cutting the porous mass length radially thereby yielding a porous mass.
