Reticulated PU Foam
High-performance open-cell polyurethane foam with 97–99% open porosity for air and liquid filtration.



Reticulated Polyurethane (PU) Foam is a high-performance open-cell foam designed for air, liquid and industrial filtration. During reticulation the cell membranes of conventional polyurethane foam are removed, leaving a strong three-dimensional network of interconnected cells. The result is exceptionally high airflow, excellent permeability, superior dust-holding capacity and outstanding filtration performance.
