Polyester Needle Felt - 1.5mm Thickness, 515g/m2 Weight | High Porosity, Excellent Dust Collection Efficiency, Long Service Life, Acid And Alkali Resistant

These Polyester Needle Felts have the advantages of high porosity, good permeability, high dust collection efficiency, long service life and so on, which are all better than the general needle felt. Furthermore, for the relatively modest of their resistance to temperature(150a ), acid and alkali, therefore, these fabrics are widely used as one of the general needle felt.

These Polyester Needle Felts are applied to the fields of metallurgy, chemical, building materials, smelting, machinery, mining, dyeing, food processing, oil, pharmaceuticals and others in the aspects of technology applications, materials recovery, dust control and the field of liquid-solid separation
