1. Operation temperature 150 Deg c, 
2. the max surge is 150 deg c. 
3. good anti-acid, good  anti-alkali ,good hydrolysis stability
4. Mean Air Permeability: 10-15 m3/m2/min@12.7mmH2O
Avaiable Finish: singed,calendar,PTFE membrane,W/O
The surface of polyetrafluorethylene (PTFE) membrane is smooth and anti-chemistry. PTFE membrane is bonded to the surface of conventional filter medium and eliminates the need for a primary dustcake. Filtration takes place on the membrane surface and realizes surface filtration. Because the PTFE membrane has the advantage of smooth , chemical stability, long service life and waterproof, it results in excellent dustcake release, high filtration efficiencies and l onger service life.
