Cellflon Brown – ePTFE Gasket Tape

Cellflon Brown – ePTFE Gasket Tape

KWO® CellFlon® brown is a gasket tape made from expanded PTFE with a silicate filler and a modified structure.

By adding the silicate and through the patented CellFlon® processing method the mechanical properties of the gasket tape are considerably improved.

The result is a substantially reduced cold-flow tendency, a clearly improved recovery and excellent sealing properties in systems with temperature cycles.

The tape features a self-adhesive backing for easy installation. The used glue has a very high adhesive force.

Advantages

  • High residual thickness at time of installation
  • Small widening
  • Highest recovery properties
  • Excellent adaptability to all surfaces
  • Excellent sealing characteristics, even in case of alternate loadings

Properties
