KWO® HD-E is gasket tape of mono-directionally expanded pure PTFE with a high density. The tape is characterised by a rectangular cross-section and a relatively small width. The high density of the material and the special cross-section of the tape allow the sealing of very uneven sealing surfaces even at a low gasket stress.
KWO® HD-E sealant tape is suitable for delicate sealing applications on surfaces vulnerable to tension, such as glass or ceramics. The tape can also be used to seal weak flanges subject to considerable deformation, for example glass reinforced plastics (GRP), plastic fittings and ventilation facilities.
