Activated carbon foam: open-cell polyurethane foam carrying activated carbon powder or granules. Air passes through the media rather than around it, so you get contact time without the pressure penalty of a packed bed.

Choosing the pore grade
PPI is the trade-off dial. Coarse pores mean low resistance and short contact time; fine pores mean the opposite. Tell us the airflow and the depth you have, and the pore grade follows from those two numbers.
One clarification worth making plainly: this is carbon-loaded PU foam, which is what the term means in air filtration. The rigid, all-carbon material used in thermal and battery work is a different product and we do not make it. Loaded foam can release fines — where that is unacceptable it ships film-laminated or die-cut as a finished part.
Foam is the low-resistance option. Where the same depth has to carry more carbon, granular carbon mesh reaches ≥80% and is the only media we publish a measured ammonia figure for. Where the space is very shallow, ACF felt works in a millimetre or two — and unlike foam, the ACF fibre is the carbon rather than a carrier for it.

Buyer questions
Frequently asked questions
Short answers drawn from the specifications on this page.
What is activated carbon foam?
It is open-cell polyurethane foam carrying activated carbon powder or granules. Air passes through the media rather than around it. It is not the rigid, all-carbon foam used in thermal and battery work, which we do not make.
What PPI activated carbon foam should I use?
Pore density runs from 10 to 60 PPI. Coarse foam gives low resistance and short contact time; fine foam gives the opposite. Tell us the airflow and the depth you have, and the pore grade follows from those two numbers.
How much carbon does activated carbon foam carry?
Typically ≥50%, and the loading can be customized. If the same depth has to carry more carbon, granular carbon mesh reaches ≥80%.
What sizes is activated carbon foam available in?
Blocks are foamed up to 800 mm and sliced to the thickness you need. Sheets are up to 1200 mm wide (1000 mm standard) and 2000 mm long, and can be film-laminated or die-cut into finished parts.

Airflow, the depth available and whether shedding matters. From those three we come back with a pore grade and thickness to compare — and material to test.
