Detailed Description

PTFE Needle Felt PTFE needle punched felt are produced from 100% PTFE fiber which has been punched in three-dimentional structure. They have excellent features such as excellent flexibility, molding capability, high tensile strength, creep resistance, high and low temperature resistance, corrosion resistance and anti-aging. 100% PTFE filter material can meet requirements in hostile environments of temperature fluctuating and acid & alkali in all PH range. The lifespan of PTFE filter material will be guaranteed for over 4 years as long as the temperature is controlled under the maximum operating temperature. Product Feature: Be composed of 100% pure PTFE; Can operate at 240 °C continuously; Acid and alkali Resistance, corrosion resistance, have strong chemical stability (0-14 PH); Can be used under high humidity environment; Low shrinkage rate even if under high temperature, Aging resistance; No enviroment pollution Application Combustion Coal burning boiler waste incineration carbon black producing Tio2 producing for fume treatment or dust collection PTFE fibres are supplied blended with glass fibres and P84 to produce FNS® Series.
