Microporous material and systems and methods for making the same

A matrix capable of passage of water therethrough having a flow rate at 20° C. that, when tested using the matrix having a thickness of 100-140 micrometers under atmospheric pressure of 1 bar, meets or exceeds a flow value produced by application of Formula 1

• Flow=k·(Bp−b0)L Formula 1:
• wherein Bp is a bubble point;
• wherein when the bubble point with water at 20° C. is between above 0.01034 and 0.25 MPa, k=31026, L=−1.00, and b0=0.01034;
• and when bubble point with water at 20° C. is greater than 0.25 MPa, k=5797, L=−1.35, and b0=0.1379, wherein the flow is expressed in L/m2/h.
