CHARACTERISTICS

---

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

 

  CELL STRUCTURE

---

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.
