Under the brand name PE-porös, KIK offers filter elements made of porous polyethylene (HDPE/ UHMWPE), for use both in liquid and gas filtration.
For use in filtering equipment of all kinds, we manufacture filter media in almost any geometry wanted, and in a wide range of filtration grades, from 1 µm to far over 100 µm.
PE-porös is manufactured by a special sintering process, in which the granules of plastic are heated until their surfacessoften, and fuse at the contact faces, while retaining more or less their original shape. The shaped body created thus has open continuous pores, whose size and number depends on the sintering conditions and the size of the polymer particles selected.
The pore size is mainly determined by the size and shape of the plastic granules employed. Sintered filters do not possess a uniform pore size; instead, they have a spectrum of pore sizes similar to a normal distribution. In order to characterize them, KIK states mean pore widths that correspond to the maximum of this distribution. A quality feature of a filter is a narrow distribution of pore sizes. The largest pores in PE-porös can be assumed to be roughly 30% to 50% larger than the mean pore size.
