Polyimides are polycondensates from aromatized monomers with particularly high heat resistance
The company Inspec Fibres manufactures these fibres and markets them under the brand name P 84®.
The fibre has good chemical resistance, but this is endangered under highly alkaline moisture conditions. There is a limited tendency to oxidation through O2 or NO2 at high temperatures.
Multilobal fibre cross-section with very high fibre surface and very good dust separating efficiency.
Typical fields of application:
|Temperature resistance||Continuous: 240 °C/Peak: 260 °C|
|Moisture pick-up||3 % at 65 % relative humidity and 20 °C|
|Resistance to hydrolysis||Good|
|Resistance to oxidation||Good|
|Resistance to solvents||Good|
