Sintered fiber felt, mainly made of stainless steel, is produced by lapping, laminating and high temperature sintering. Compared with woven wire cloth, sintered fiber felt has better filtration function, because it has high porosity, excellent permeability, dirt holding capacity and filtering accuracy. With high strength and long service life, it is widely added into various sintered wire mesh products for a filtering layer, it also can be sintered with multiple fiber felts to form filter media.

Stainless steel sintered fiber felt is a kind of fiber net sintered by high temperature. It has a high strength and still keeps a three-dimensional reticulated porous structure. Besides, it has a high porosity and the bore diameters are distributed evenly. Therefore, it overcomes the metal nets' shortages of easy to block and be damaged; solves the filter paper's problems of not resisting temperature and pressure. All in all, the stainless steel sintered fiber felt is an ideal filter material and it is widely used in petrochemical industry and other industrial places.
