Introduction of PTFE Filter Fabric
PTFE needle felt has smooth surface and resistance to chemical stability. sustained operating temperature above 250℃. instant temperature 280℃,not afraid to pH and oxidation. almost non-flammable. does not age; meet the most adverse conditions. with extremely long service Life. Normally,the working Life is 4 years.
Feature of PTFE Filter Fabric
PTFE filter which made use of special techniques and different film laminated fabric, has excellent chemical stability, smooth surface and easy cleaning, good air permeability, high temperature, excellent resistance to condensation function.
Application of PTFE Filter Fabric
It is mainly used in these fields such as chemical industry, waste incineration, smoke collection, high temperature liquid filtration, industrial exhaust treatment, dust.
