Reticulated polyurethane foam filter.

Filter foam with a medium porosity 45 ppi works as a depth loading filter opposed to a surface loading filter trapping dust particles within its cell structure. It is also used as speaker foam due to the high air flow its structure allows. With an open cell structure and three dimensional skeletal strand structure. As a manufacturer of filter foams we supply untreated and processed foams.

The majority of the components we manufacture are best suited for the mid range ppi. Volz made this discovery back in 1956 whilst working for a sanitary tissue company. Reticulated foams for filtration reticulated foams with a particularly high homogeneity for numerous special applications our filtration foams are used as filters for liquids and gases and are used as a carrier medium in ceramic filters catalysts and battery electrodes.
