When evaluating the performance of high-temperature PTFE tape, initial tack and holding tack are two easily confused yet distinctly different properties. For applications involving high-temperature PTFE tape, the difference between them directly determines whether the tape is suitable for quick positioning or long-term fixation.
To help users better understand, the fundamental differences between initial tack and holding tack of high-temperature PTFE tape are compared in the table below:
Comparison Item | Initial Tack of High-Temperature PTFE Tape | Holding Tack of High-Temperature PTFE Tape |
Definition | The ability to resist separation immediately upon light pressure and short time contact. | The ability to resist slipping and peeling after full bonding under continuous load. |
Performance | Bonds instantly upon application, no edge lifting, easy positioning. | Remains stable without shifting or degumming even under long term stress and heat. |
Performance Focus | Focuses on the instant wetting speed of the adhesive. | Focuses on the long term cohesive strength of the adhesive layer. |
Testing Method | Measured by the largest steel ball grade that the tape surface can hold. | Measured by the slipping time or distance under a suspended weight. |
In summary, initial tack of high-temperature PTFE tape determines how quickly it sticks, while holding tack determines how long it lasts.
