What is PPI for foam?
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.
What is PPI aquarium?
Aquarium Foam Filters and Pond Foam Filters PPI, which stands for ‘Pores per Inch’, indicates the number of holes/cells per inch of filter foam.
What is 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.
What kind of foam is used in aquarium filters?
open-cell polyurethane foam
Aquarium Filter Foam and Sponge Filson aquarium foam filter also called aquarium sponge, Filson aquarium foam filter material is open-cell polyurethane foam which has a much larger surface area for filtration capacity. Filson aquarium foam filter can remove the unwanted particulates from the water.
What is reticulated foam made of?
Reticulated ceramic foams are made by coating a reticulated polyurethane foam with an aqueous suspension of a ceramic powder then heating the material to first evaporate the water then fuse the ceramic particles and finally to burn off the organic polymer.
What PPI is coarse foam?
The size of pores is measure in pores per inch (ppi). The foam with higher ppi has more pores in it. More pores mean larger biological filtration capacity but faster clogging. A coarse foam will be 20 ppi, a fine foam will be 40 ppi.
What is non reticulated foam?
Closed cell (non-reticulated) foams are completely sealed with cell windows intact. Closed cell foams generally exhibit higher density, greater durability and reduced absorption versus open cell foams.
Does sponge filter provide oxygen?
And despite their reduced capacity for surface agitation sponge filters provide plenty of gas exchange thanks to the constant flow of air bubbles. Both oxygen and carbon dioxide can be transferred in meaningful enough amounts for both fish and plants to thrive.
How do you make reticulated foam?
What is Aquarium sponge made of?
These include synthetic wools, known in the aquarium hobby as filter wool, made of polyethylene terephthalate or nylon. Synthetic sponges or foams, various ceramic and sintered glass and silicon products along with igneous gravels are also used as mechanical filter materials.
How long does poret foam last?
Long life, 5-10 years and more! High compression strength to prevent shrinking. Hydrophilic surface facilitates colonization by beneficial microorganisms. Perfect as a biofilm carrier for biofilters.
How do you cut poret foam?
Poret foam is very strong and rigid but it`s no match for a sharp knife. To cut Poret you will need a cutting edge that is very sharp. We like using a box cutter with a long blade it is a good idea to run the blade along a flat metal edge like a bit of boxed aluminium.
