LSP 90/AFF is a reticulated polyuretherane foam (Polyester based); the cellular network is entirely open and does not contain any closed cells. This is obtained by a thermal reticulation process by which all cell membranes which still remain after the foam formation are melted into the cell ribs.

Thanks to its calibrated cell size, the homogeneous cellular structure and the three-dimentional network, this foam is an ideal support for filtration and prefiltration of air in the automotive industry, air conditioning and ventilation. The calibrated cell size and openess ensure a reproducible filtration efficiency, while the three-dimensional network allows a high dust load without affecting the pressure drop significantly. Finally, the foam can be shaken, washed, rinsed...and can thus be reused many times.

The volume taken by the foam ribs only represents 3% of the foam volume. It is not subject to "swelling" in the presence of water, fuel, soaps and detergents, mineral oils, greases etc. However, most of the organic solvents swell the foam, the extent of the swelling varies from one solvent to another.
