Many of you will recognize this for what it is, a reticulated hydrophobic PU foam originally developed as an air filter. It is used in many ways including in the fuel tanks of fighter jets and race cars.

Tracing their origin back to air filters, reticulated foams are differentiated by pore size from 1 cm to 250 µm. They are made commercially using a hydrophobic polyol and toluene diisocyanate using the “one‐step” process described in the chemistry chapter. Pore size is very carefully controlled. This is followed by the reticulation step described earlier.

This is not a comprehensive list of manufacturers, but reticulated foams are produced in the United States, by Crest Foam (Moonachie, NJ) and FXI (Media, PA). Recticel in Belgium produces these foams as does Inoac in Japan.

For our purposes it is the basis for the development of a set of specifications. We have compiled them in Table 3.10.
