Technical Data

DESCRIPTION

MC&S Brand Porous Structures are porous engineering materials consisting of tiny, precisely-sized spherical particles bonded together to form rigid three-dimensional shapes having an evenly distributed network of interstitial pores which are of uniform size, completely open and interconnected.  Porous structures are manufactured using a patented process, which permits the exact reproduction of specified pore size, pore distribution and physical dimensions, regardless of quantity ordered over time.

USES

MC&S Brand Porous Structures are ideally suited for a wide variety of applications involving filtration, aeration, oxygenation and fluidization — to name a few.  They are intended for use wherever high rates of gas transfer into liquids, low back pressure, precisely controlled/evenly distributed flow rates or other desirable performance characteristics of uniform porosity are required.

AVAILABILITY

MC&S Brand Porous Structures are immediately available in flat sheets, hollow tubes, solid rods and an almost limitless variety of simple or complex/compound custom molded shapes to meet your design specifications.  The following standard grades are normally stocked.  Grade designations used to identify MC&S Brand Porous Structures also denote the maximum interstitial pore diameter in microns (ASTM 128-61).  Coarser and finer grades available upon request from MC&S:
