KWO® CellFlon® Tape – ePTFE gasket tape
KWO® CellFlon® Tape is a gasket tape made from expanded virgin PTFE with a modified texture. The gasket tape is particularly suitable for demanding and very clean applications, for example in the food industry and in the pharmaceutical manufacturing sector.
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.
These characteristics allow a wide range of applications, regardless of the shape and the size of the sealing surface.
