Pe Sintered Filter

PE sintered filter are made from spherical PE powder. the form, size and distribution of the powder are important parameters which affect the filters' properties.

There are two main types of sintered PE filters as Hydrophilic & Hydrophobic

PE sintered filters are produced using the gravity sintering method. the PE powder is placed in a mold and sintered.

During sintering, the powder particles are fused to one another at temperatures well below the melting point of the material. this process gives the highly porous filters their characteristic shape and properties.

After sintering, the size and position of the pores are mechanically fixed. the powder particles also form a rigid whole. this gives the filters a strength, form and stability equal to those of a plastic component.

Porous sintered products are a depth-filtration medium with distribution of pore size and length of passage qualities that are a factor of particle size, shape, and part dimension. The depth-filter not only has more dirt-holding capacity that a screen filter, but also has a higher pressure drop than a screen of equivalent porosity rating.

Porous P/M parts are capable of extremely fine degrees of filtration. The subject of absolute vs. nominal filtration or micron ratings is too complex to be treated here; it is so complex, in fact, that much of the filter design in P/M porous media on new applications has been performance oriented (actual test of samples) rather than based on theoretical design data.
