multiFlon® Tape HP
multidirectional expanded PTFE gasket tape of the new generation
multidirectional ePTFE gasket from the spool, with improved properties, TA-Luft certified – FDA compliant
multiFlon® Tape Style HP is the new generation of multidirectionally expanded PTFE gasket tapes for use in metallic pipelines and apparatus flanges.
The optimised fibre structure of this new material leads to significantly improved creep resistance and lower settling behaviour compared to previously used products.
multiFlon® Tape Style HP is self-adhesive on one side, flexible and compressible. Due to the good deformability, the seal adapts optimally to flange unevenness and roughness.
multiFlon® Tape Style HP is made from 100% pure ePTFE and therefore offers optimum durability, even in the most demanding applications.
Thanks to the use of the highest quality raw materials and regulated production, this gasket tape is also available as a GMP-compliant material.
Typical applications
- Components
Agitators, columns, pumps, housings, all large flange connections, also with higher unevenness, boilers (for TRD401)
use the seal specially approved for this purpose) as well as heat exchangers in various industrial sectors. - Flanges
all flange types in force main connection - Sealing surfaces and materials
Steel, aluminium, titanium, Inconel® and other metallic alloys
