Pre filter foam sponge
Filter foam, also known as reticulated foam, is a porous, low-density, reticulated flexible polyester/polyether urethane foam. With an open cell structure and three dimensional skeletal strand structure. Available in pore size grades from 15PPI through 100PPI, in sheets or roll form.
Filter sponges can be widely used in daily life and industry such as communication equipment, home appliances,automotive industry, the air-conditioner industry, hardware industry, medical equipment industry, instrument tools, bags, furniture, children’s educational toys, physical education equipment, housewares and so on.
It’s divided into beginning effect filter foam,amid effect filter foam and high effect filter foam according to the porosity and usage.Concretely,it can be used in filtering,dustproofing,dedusting and adsorbing,etc.

CHARACTERISTICS
Filter foam, also known as reticulated foam, is a porous, low-density type of polyurethane foam with an open-cell structure. Filter foam has a near-infinite amount of applications due to the following characteristics:
· Compressibility
· Energy absorption
· Fabricatibility
· Flexibility
· Lightweight
· Low thermal conductivity
· Low water vapor transmission
· Mildew-resistance
· Resiliency
· Sound absorption
· Vibration dampening
CELL STRUCTURE
Filter foam operates as a depth-loading filter, as opposed to a surface-loading filter, essentially trapping dust particles within its cells.
The cell structure of filter foam is remarkable in that each cell has a dodecahedron shape (12 sided), the cell’s walls or “struts” are comprised entirely of organic polymers (polyurethane, polyether, polyester) & the empty space or “windows,” between each strut, comprise 95% – 98% of the filter foam’s mass.
The size, shape & distribution of cells within filter foam can be manipulated during manufacture to provide precisely the desired porosity level, measured in PPI or pores per inch.
