Abstract:
1. A method for producing a filtration matrix comprising the acts of: providing a plurality of a first polymer particle, wherein the particles have a convoluted structure and an average particle size of about 30 to about 40 microns, the first polymer particles being perforated, the plurality of first polymer particles comprising polyethylene having a molecular weight greater than about 750,000; providing a plurality of at least a second polymer particle having a generally spherical, non-porous structure and an average particle size of about 30 to about 65 microns; providing a filtering material; blending about 10% to about 65% by weight of the first polymer particles, about 0.5% to about 65% by weight of the second polymer particles and about 30.0% to about 75% by weight of the filtering material together; and processing the resulting blend such that a structural matrix is formed thereby.
