Polytetrafluoroethylene Fibre (PTFE)

Polytetrafluoroethylene Fibre (PTFE)

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.
