SK305 is a sealing material based on Polytetrafluorethylene (PTFE)
and it is widely used at dry-running compressor services. The main
application is the compression of Oxygen. Therefore, the material
was tested and certified by the “German federal institute for material
research and testing” (BAM certification). An optimized concentration
of fillers and lubricants within the PTFE matrix ensures
high service life-times and increased mechanical properties, while
providing an outstanding resistance against oxidation reactions.
