KWO® Universal FR

ePTFE gasket tape with fillers

KWO® Universal FR is a gasket tape made from glass fibre reinforced expanded PTFE. 

The added glass fibres improve the mechanical properties and allow a higher operating temperature. The result is a considerably reduced cold-flow tendency, good recovery properties and excellent sealing performances at thermal cycling’s.
