PTFE sealants and tapes
Features
Self-adhesive sealant tape made from 100 %
Teflon
®
PTFE. The production process
creates a micro-porous, mono-directional
fiber structure (ePTFE), that gives the seal
its special properties. Universal 100 %
virgin PTFE flange sealant tape which has:
• Expanded microcellular structure
• Very good adaptability
• Easy to install – tape has adhesive
backing to fix into position
Advantages
• The sealant tape, self-adhesive on one
side, shows the highest adaptability of all
PTFE seals. The adhesive strip protected
by a masking paper on the rectangular
seal face makes fixing the sealing tape to
the flange surface very easy and simple
• Extremely easy to handle and applicable
almost anywhere for all kinds of flange
styles, sizes and construction shapes
Operating range
Temperature: t = –240 °C ... +270 °C,
transient peak up to +315 °C
Chemical resistance: pH = 0 ... 14

Standards and approvals
• BAM (O

Notes
The pressure resistance depends only
on installation and operating conditions.
Please check our installation and
maintenance instructions. With the self
adhesive strip on one side, the tape is
easy to install. The sealant tape is not
subject to aging. The adhesive life depends
on the storage and installation conditions.

Seal selection and installation dimension recommendation
The correct choice of the seal’s dimension depends on factors like width and composition
of the sealing surface, on construction of flanges and bolts as well as on the existing
operating conditions. Rule of thumb: Seal width should be approx. 1/4 to 1/3 of the sealing
surface width.

<6.3 μm
On standard surfaces with higher roughness, as a rule, the
increase in width is smaller which results in higher surface stress.
This causes also higher thickness in service.
