What is PTFE Filter Felt Filter Bags ?

ECOGRACE  is specializing in production of filter needle felt and filter bag processing, design and manufacturing dust collecting system in China.


PTFE  filter needle felt dust filter bags are mainly for dedusting for waste treatment plant .
 (Polytetrafluoroethylene ) PTFE Filter Media  with Dipping ,PTFE membrane .
 
100% PTFE Filter Needle Felt Application :
PTFE filter bags  are suitable for the corrosion resistance of harsh condition that require a longer working life of dust collector filter bags , such as waste incineration flue gas filtration, coal boiler power plant ash handling system , waste treatment plant .
 
100% PTFE Filter Needle Felt  Performance :
Excellent chemical stability and heat resistance
Will withstand all strong acids and alkali erosion
Will serve well for gas continuous operating temperature up to 240°C, instant temperature up to 280°C.
Will withstand all kinds of strong oxidant corrosion
Hydrolysis performance is excellent;
 
Good flame retardant, insulation, heat insulation, light stability, low coefficient of friction and small adhesion.
PTFE filter cloth has excellent filtration efficiency, low and stable differential pressure, easy cleaning, and under the same conditions its life is significantly longer than other high temperature resistant filter materials.
