TFE film-covered needle-punched felt is a composite filter material made of PTFE microporous film on the surface of the original needle-punched felt filter material. In addition to the characteristics of the filter material itself, PTFE film-covered needle-punched felt is also resistant to various chemical corrosion, hydrolysis, hydrophobicity and condensation, ultraviolet and high temperature resistance, good dust removal efficiency and other characteristics. It has high filtering accuracy. The total dust collection rate of 0.01-1.0 um can reach 99.999%. The emission concentration can be reduced to less than 10 mg/Nm3 with ultra-low emission.
