Cellflon White – ePTFE Gasket Tape

Cellflon White – ePTFE Gasket Tape

KWO® CellFlon® white is a gasket tape made from expanded virgin PTFE with a modified texture. The gasket tape is particularly suitable for demand¬ing and very clean applications, for example in the food and beverage 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. The self-adhesive tape can be easily stick to the flange. The used glue is suitable for applications in the food industry.
