Filter foam sponge, also known as reticulated sponge, is a porous, low-density, reticulated flexible polyester/polyether urethane sponge. With an open cell structure and three dimensional skeletal strand structure.

Filter foam, also known as reticulated foam, is a porous, low-density type of polyurethane foam with an open cell structure. Filter foam has a near-infinite amount of applications due to the following characteristics:
· Compressibility
· Energy absorption
· Fabricatibility
· Flexibility
· Lightweight
· Low thermal conductivity
· Low water vapor transmission
· Mildew-resistance
· Resiliency
· Sound absorption
· Vibration dampening
Filter foam operates as a depth-loading filter, as opposed to a surface-loading filter, essentially trapping dust particles within its cells.
The cell structure of filter foam is remarkable in that each cell has a dodecahedron shape (12 sided), the cell’s walls or “struts” are comprised entirely of organic polymers (polyurethane, polyether, polyester) & the empty space or “windows,” between each strut, comprise 95% - 98% of the filter foam’s mass.
The size, shape & distribution of cells within filter foam can be manipulated during manufacture to provide precisely the desired porosity level, measured in PPI or pores per inch.
