Description

Reticulated Foam

Applications

Common applications for filter foam include speaker covers, filters, and cleaning sponges.

Advantages

Filter foam is good-quality foam with a medium/firm feel. Filter foam has a high dust collection rate, while still providing high air flow. It operates as a depth-loading filter, as opposed to a surface-loading filter, essentially trapping dust particles with its cells. It is the ideal material for applications where porosity, surface area and low-density are integral for success.

Type

Porous, low-density polyurethane foam

Available Forms

Filter foams are available in bun, roll and sheet forms, porosities ranging from 10 PPI (coarse) to 100 PPI (fine) and those colors most requested: Charcoal (black) and white.

Density ranging from 1.20 lb/ft to 1.5 lb/ft

The different pore sizes are shown in the picture below, comparing 10 PPI (bottom piece) and 80 PPI (top piece) filter foam.
