Flumex needle felt is a well-structured one. The new high-tempera-ture and high-efficiency filter material with excellent performance notonly has the advantages of high temperature resistance, acid and alkalicorrosion resistance, dimensional stability and high strength of glassfiber woven filter material, but also uses 100% alkali-free glass fiber asraw material, using high thread count glass fiber filament, and is madeof filamentous needle punching, which has good heat resistance, flameretardant, anti-corrosion effect, small gas filtration resistance, dustremoval efficiency exceeds that of woven filter material, and the filtra-tion speed is about twice that of woven filter material, which is thepreferred product for purifying blast fumace gas and flue gas filtrationin steel, refining and other industries.
