Product Introduction
Powder Sintered Filter Elements are microporous metal filtration materials, manufactured from irregular stainless steel powders through cold isostatic pressing, mold pressing, or extrusion. As a result, they offer excellent permeability and filtration precision. Moreover, they provide high strength and toughness while operating at temperatures up to 300℃. Therefore, they are widely used in petroleum, chemical, and environmental industries as filtration materials, porous electrodes, sound-absorbing components, shock absorbers, cooling materials, catalyst carriers, and anti-freezing components.
Materials and Forms
Materials Available: SUS304, 304L, 316, 316L.
Forms: Tubes, plates, discs, rings, rods, and cones.
In addition, these options give customers flexibility to choose the most suitable form for their application.
