MC&S Brand Porous Structures are available as blocks, cylinders, and sheets in five different grades: 15, 40, 55, 90, and 175. Grade number refers to the maximum pore diameter in microns (micrometers). The end use will determine the pore size or grade best suited for your requirements. All grades are resistant to a wide variety of chemicals. Please contact us for the complete list of chemicals.
Shapes can be machined to close tolerances. Pores are not clogged by binder flow during machining. Surfaces can be sanded smooth with common coated abrasives and easily cleaned with a brush or compressed air. Material can be sealed or bonded to itself, metal or other materials. It can also be formed in place — in a tube, pipe fitting or similar holder.
