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.

Listing Description
1）Acid and alkali Resistance, corrosion resistance,aging resistance
2）Can be used under high humidity environment
3）Low shrinkage rate even if under high temperature 260℃

Application
Combustion Coal burning boiler
Waste incineration Carbon black producing
Tio2 producing for fume treatment or dust collection
PTFE fibers are supplied blended with glass fibers and P84 to produce FMS Series
