Reticulated Polyurethane Foam Filter
Available in pore size grades from 15ppi through 100ppi in sheets or roll form.
Reticulated polyurethane foam filter. Everyone has seen or used filter foam in the aquarium hobby it s everywhere here s a quick look at how it s made and why the reticulation process is so imp. The solid component of a reticulated foam may be an organic polymer like polyurethane a ceramic or a metal these materials are used in a wide range of applications where the high porosity and large surface area are needed including filters catalyst supports fuel tank inserts and loudspeaker covers. Order die cut polyurethane reticulated foam components filters at frank lowe we offer a full range of different reticulated foams with ppis spanning from as low as 4 up to 100. Choose from our selection of reticulated foam including over 110 products in a wide range of styles and sizes.
In order to make this type of foam a regular closed cell polyurethane foam must first be. Characterized by a skeletal structure of strands which provide a constant 97 percent void space and a very high degree of permeability. 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. The majority of the components we manufacture are best suited for the mid range ppi.
A reticulated open pore flexible ether type of polyurethane foam. 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. The person first credit with discovering the production process for making reticulated polyurethane foam is robert a. Filter foam is a reticulated polyurethane foam specially adapted to air and liquid filtration in a range of controlled cells from 10 pores per inch to 100 ppi.
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. This foam is dark charcoal. With an open cell structure and three dimensional skeletal strand structure.
Filter foam also known as reticulated foam is a porous low density reticulated flexible polyester polyether urethane foam. Volz made this discovery back in 1956 whilst working for a sanitary tissue company. As a manufacturer of filter foams we supply untreated and processed foams.
