Description
Features PTFE needle felt also called Teflon, with a good performance in the temperature of 260 centigrade, the instant temperature can up to 280 centigrade. PTFE is a special material with a good alkali and acid resistance ,anti-hydrolysis ,stable physical dimension, mainly used in coal burning boiler, waste incineration ,carbon black producing,Tio2 producing for fume treatment or dust collection, as well as some high temperature or some corrosive liquid filtration. Note:1. special specification can be customized. 2. maximum width:2.2meters. 3. both filter cloth rolls and filter bags are available from Shanghai sffiltech. Features of PTFE needle felt： Working temperature is under 260 degree Can be used under moisture, high harsh chemical working condition Advantages of PTFE needle felt： a) High temperature resistance b) Excellent acidity resistance c) Excellent alkalinity resistance, d) High filtration fineness Working principle of PTFE needle felt: It will be sewn to PTFE filter bag for bag houseTechnical Data PTFE needle feltConstructionNeedle feltmaterialPTFE needle feltSrim supportYesFelt Area Weight750g/sqm +/-5%Thickness1.2-1.4mmMean Air Permeability8-16 m3/m2/min@12.7mmH2OBreaking Strength-MD（warp）800（N/200×50mm）Breaking Strength-CMD（weft）900N/（N/200×50mm）Breaking Elongation( N/5cm)-MD（warp）20%Breaking Elongation( N/5cm)-CMD（weft）25%Dry Shrinkage MD（240℃warp）＜2.5%Dry Shrinkage CMD（240℃weft）＜1.5%Operating Temperatures220-250 deg CRecommended Maximum Continuous250 deg CRecommended Maximum Surge270 deg CFinishSinged,calendered,heatset,PTFE membrane
