Porous Plastics Filter Elements

We offer porous sintered filter elements in various shapes and sizes viz., discs, domes, and hollow cylinders for filtration of water, air and chemicals. The separation mechanism of filter elements is primarily due to deep-bed filtration. The materials of construction are inert polymer alloys to suit the operational conditions like fluid medium, temperature and pressure as well as high chemical resistance. The filter elements are available in pore sizes ranging from 1-250 microns. [nominal rating] the material used is a free-sintered material that produces porous plastic products with excellent filtration efficiency of fine solid particulate combined with excellent flow ability of liquids and gases. Controlled particle size distribution and a precise temperature cycle are used to produce a wide range of interconnected cell structures and specific pore size ranges. These pore structures are designed and controlled to function in a variety of applications such as filtering, wicking, diffusing or venting gases, and sound muffling. The material used is naturally hydrophobic, however, the material can be treated to produce hydrophilic properties allowing wicking of aqueous solutions. In addition, special formulations can act as a self-sealing material in the presence of aqueous solutions. Porous plastics retain most of the physical properties of their solid counterparts, but also offer a unique set of properties. The unique "tortuous filtration path" of the material produces high filtration efficiency combining the properties of both surface and depth filters. Porous plastics have excellent resiliency; high physical strength and lightweight providing a rugged easily handled part. Filtration efficiencies of 99.8% can be achieved.
