Polyester Filter Foam - Structure

Polyester filter foam is a cell-controlled, reticulated polyester foam with a defined and uniform pore size, defined in pores per linear inch, or “PPI.” The reticulation process removes the cell membranes and leaves a lightweight, porous and strong three-dimensional net-like structure.

The temperature resistance is -40° to 212° F (293° F for short periods).
