KWO® CellFlon® CL

ePTFE gasket tape

 

KWO® CellFlon® CL is the optimised gasket tape for a safe and cost-effective use in chlor-alkali electrolysis-cells.

The micro-cellular structure of the modified ePTFE material ensures very good sealing properties for long lasting application in frames of electrolys-es cells.

The patented CellFlon® processing method improves considerably the mechanical properties and strengthens the fibre structure. Consequently, the tape is much more compact and has a lower cold-flow tendency as well as better recovery properties.
