PPS + PTFE needle felt

PTFE coated PPS filter bag refers to the high-performance filter material made of PTFE microporous film covered with a special process and different base cloth
It has excellent chemical stability, smooth surface, easy ash removal, good air permeability, high temperature resistance and excellent anti condensation function, especially for the environment with high concentration and high humidity, high adhesion dust and high emission requirements
The use of membrane filter material can realize surface filtration
The dust will not penetrate into the fabric (filter material) and bag blocking will not occur
The filtration efficiency can reach 99
999% (close to zero emission)
It is widely used in all kinds of bag filters for flue gas purification and material recovery, and the effect is excellent Fiber composition PPS + PTFE base cloth composition PTFE gram weight 550-600g / m2 thickness 1
