PPI filtration foamPPI filtration foam An open-pore, flexible polyurethane foam on a polyether/polyester base. Grades/types 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 - or polyether basis. PPI filtration foam on a polyester base should not be used in proximity to water or other humid surroundings, as there is otherwise a risk of decomposition. However, PPI filtration foam on a polyether base is suitable for applications in humid environments or water filtering. Applications For filtering dust, water vapor, drifting snow etc., or as a filter and lining in loudspeakers. Has limited durability in direct sunlight.  Type PPI 10 PPI 15 PPI 20 PPI 45 PPI 60 PPI 80 type Polyester-based poly-urethane-foam  Polyester-based poly-urethane-foam  Polyeste-rbased poly-urethane-foam  Polyester-based poly-urethane-foam  Polyether-based poly-urethane-foam  Polyester-based poly-urethane-foam Colour Black  Black  Black  Black  Black  Black +100 °CProduct- and material overviewProduct overviewMaterial overview Industry / OEMBuilding Materials CVR nr. : 40088873DAFA US Inc.

   >   Frequently Asked Questions   >   What is Porosity? – Universal Air Filter Why is Porosity important to air filters using foam media? Open cell, reticulated, Polyurethane foam is a great material for filtering unwanted particulate from the air.  It has a pentagonal, dodecahedron geometric shape that is controlled in the manufacturing process and may be varied to meet specific applications.  These shapes are referred to as pores.  The term porosity, measured in PPI (Pores Per Inch) designates the number of pores  in one linear inch.  Counting the pores is a visual indication of porosity which directly coincides with an airflow tested measurement that defines a range of airflow for a given porosity. What does all this mean to you and your air filter application?  In general, with thickness being equal, the higher the porosity, the more pressure it takes to pull or push air through the foam filter media.  For example, 10 PPI foam has large pores, approximately 0.10” in diameter and offers very little resistance to airflow.  Consequently, it is not very effective at capturing small particles and arrestance values are typically below 50%.  By comparison, 60 PPI foam,  has small pores, approximately 0.015” diameter.  The resistance to airflow can be quite high, especially  if thickness is greater than 0.50”.  However, arrestance values can reach well into the 90% range.  The average home furnace filter ranges from 65% to 90% arrestance. Air filters use reticulated foam media, capture dust particles by obstructing their path and causing them to become  captured in the cellular structure.  By varying the depth of the foam filter media, you can enhance the ability for dust to “depth load” instead of merely “face loading” like higher MERV rated paper and synthetic media Face loading increases pressure drop more rapidly than depth loading.  Foam filter media is offers the added benefit of being cleanable by vacuum and washing with warm water.

Home > Materials > Foam > Reticulated Polyurethane Foam Reticulated polyurethane foam is a versatile, open-cell material that is light weight, low odor and highly resistant to mildew. It's typically used to make products that are involved in filtration, sound absorption, fluid management, wiping and padding. This family of materials features high tensile, elongation and tear characteristics. UFP Technologies has designed and fabricated a host of solutions using reticulated foams. This includes liquid delivery components for medical devices, sound absorption components in automobiles, cosmetic applicators, air conditioner filters, and sponges. Reticulated polyurethane has a high resistance to chemicals, which makes it an ideal material for filtration applications such as in lawn mower engines or wipes used in clean rooms. The porosity of reticulated foams is vital when designing a custom component or product. UFP Technologies' technical expertise will help guide you when selecting the proper material for your component. Foam technology involves the manipulation of thousands of plastic bubbles (called cells) of precisely controlled sizes. Reticulation is a post process in foam manufacturing that removes the window membranes of the cell. The cells that make up the foam can have a number of variations, which can also be precisely controlled. Different foams have varying cell structures and characteristics, but foams from the same material family can also be made with vastly different density and firmness specifications that will greatly affect their performance.
