F-Series tapes

F-Series tapes combine the high compaction forces of polyester film with the high-temperature release characteristics of a PVF (Tedlar®) coating from DuPont®.

The tape has a PVF release layer fused to one side of the film, specifically designed to provide uniform release characteristics with zero transfer of the coating to the underlying composite part. Due to the uniform PVF coating, the tape can provide consistent release at temperatures at and above the 170°C max temp of our PTFE coated tapes.

F-Series tapes can be used in both advanced composite and electrical coil applications as a lower cost alternative to pure PVF film. The product offers our best combination of compaction and release characteristics at elevated temperatures. Dunstone F-Series Hi-Shrink Tapes are offered in .002” thick, 10% shrink, and .002” thick, 20% shrink versions.
