Reticulated Filter 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. 


Filter sponge can be widely used in daily life and industry such as aquarium or pond filter,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, house wares and so on.

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




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 (polyurethanepolyetherpolyester) & 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.
