Specifications:

PTFE material also called material,with a good performance in the temperature of 240 centigrade,the instant temperature can up to 260 centigrade. PTFE is a special material with a good alkali and acid resistance,non-hygroscopic,stable physical dimension, mainly used in coal burning boiler,waste incineration,carbon black producing,Tio2 producing for fume treatment or dust collection.

Notices:

PTFE needle 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.
