PPI (pores per inch) indicates the number of cells in the foam per inch. The standard range is 10-80 PPI. PPI 10 has large cells and is completely open, while PPI 80 has small cells, is more dense, and has a lower air flow. PPI filtration foam is also available on a polyester - …

Flexible polyurethane foam is designed to perform several different functions or combinations of functions, such as holding materials (reservoirs), transporting or carrying liquids (wicking), releasing ingredients (applying), and picking up residue (wiping).

Filter foam is a porous, low-density, reticulated flexible polyester/polyether urethane sponge. With an open cell structure and three dimensional skeletal strand structure. Available in pore size grades from 10PPI through 100PPI, in sheets or roll form.

Reticulated polyurethane foam is a very porous, open-cell, low-density polyurethane foam. This foam type undergoes a thermal reticulation process that removes the window cell membranes. This post process strengthens and reinforces the foam walls and …

PPI (pores per inch) indicates the number of cells in the foam per inch. Standard range is 10ppi – 80ppi. PPI 10 has large cells and is completely open, while PPI 80 has small cells, is more dense and has a lower air flow. We can offer a wide range of filtration media based on reticulated foams.

Characteristics: A reticulated, open-pore, flexible, ether-type of polyurethane foam. Characterized by a skeletal structure of strands which provide a constant 97 percent void space and a very high degree of permeability.

Filter foam is the ideal material for applications where porosity, surface area & low-density are important for success. In addition to fabricating filter foam products to custom designed specifications, New England Foam stocks filter foam in buns, in porosities ranging from 10 PPI or pores per inch (coarse) to 10 PPI (fine) & those colors most ...

As standard, we offer our filter foams in both ether and ester varieties in 10 - 90 ppi. Send request! Our highly elastic PUR - ether foams generally (as conventional foams and also as filter foams) have a relatively good resistance to commercially available acids and alkalis.

Reticulated foams are available in a wide range of porosity, which is measured in PPI, or Pores Per (linear) Inch. There are two methods of reticula-tion: Thermal, and Chemical. U-Foam offers both variants of Retic-ulation Chemical and Thermal in P Typical applications include filtering and controlled liquid delivery.

Filter foam is a reticulated flexible polyester urethane foam. Unlike ordinary urethane foam, it has a three-dimensional structure of skeletal strands which gives it unique filtering properties. It is exceptionally porous and permeable; therefore it is ideal for many filtration applications where other foams cannot be used.
