Teadit® 25 BI

This top of the PTFE joint sealant tape belongs also to the group of multi-directionally expanded PTFE sealing materials. Again, a very complex production process ensures equal rigidity in longitudinal one cross direction, resulting in high dimensional stability and extremely low cold flaw, combined with excellent malleability and very handling. This make TEADIT® BI particularly well suited for use with all pressure sensitives and stress connection, if also compensates for irregularity and/or damages on the sealing areas.

Advantages
