Due to the infusibility of PTFE a cost intensive production process is necessary. In return the fiber has an outstanding thermal and chemical stability.
PTFE-needlefelts have high area weights owing to the high specific gravity of the fiber. New KAYSER-surface finishes ensure unprecedented filtration efficiency.
Typical fields of application:
|Temperature resistance||Continuous: 260 °C/Peak: 280 °C|
|Moisture pick-up||0 % at 65 % relative humidity and 20 °C|
|Resistance to hydrolysis||Excellent|
|Resistance to oxidation||Excellent|
|Resistance to solvents||Excellent|
