reticulated open cell mesh filter foam sponge
 
Filter foam sponge, also known as reticulated sponge, 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 60PPI, in sheets or roll form.
 
Filter foam sponge can be widely used in daily life and industry such as communication equipment, home appliances, automotive industry, 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 sponge, amid effect filter sponge and high effect filter foam sponge according to the porosity and usage. Concretely, it can be used in filtering,dustproof,dedusting and adsorbing,etc.
 
Filter foam sponge 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 sponge 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 sponge’s mass.
The size, shape & distribution of cells within filter sponge can be manipulated during manufacture to provide precisely the desired porosity level, measured in PPI or pores per inch.
