A woven glass cloth impregnated with polytetrafluoroethylene and a silicone adhesive which provides a release surface for sealing and bonding.
The glass cloth backing provides extra strength.
For use in composite moulds as a release barrier in autoclave operations.

| Tape 5453 is applied directly to moulds and is removed after the curing process if needed. |
| |
| PTFE offers a low surface energy film that has no affinity for the epoxy prepreg chemistries and acts as a release film while offering a very high degree of conformability. |
| |
| This is an important characteristic, because most moulds are not flat and the film must conform to the mould. |
| |
| Tape 5453 is applied to the tool for its release properties, there where it is inconvenient to apply release coating. |
| |
| Tape 5453 is also used to protect parts during thermal metal spray operations (see also tape 470). |
