How to choose the adhesive type for PTFE Film Adhesive Tape?
1. Silicone adhesive: Higher temperature resistance (-50°C~260°C), suitable for high temperature environment.2. Acrylic adhesive: Strong initial adhesion, suitable for medium and low temperature scenes from room temperature to 150°C.
How to solve the problem of PTFE film adhesive tape edge warping?
Reasons:1. Bubbles or uneven tension during lamination.2. Large temperature differences in the environment lead to differences in thermal expansion.Solutions:3. Use a roller to compact the tape to ensure there are no bubbles.4. Choose a thickened PTFE film adhesive tape with a low coefficient of thermal expansion (CTE).
What surface treatments are required before bonding?
1. Clean the surface: remove oil and dust (it is recommended to wipe with isopropyl alcohol).2. Roughening: Smooth surfaces (such as glass and metal) can be lightly polished to enhance adhesion.3. Preheating: The substrate can be preheated to 50~80°C before high-temperature application (to enhance the activity of the adhesive).
How to remove PTFE Film Adhesive Tape?
1. Peel slowly at room temperature. The residual adhesive can be cleaned with PTFE-specific solvents (such as perfluorohexane).2. After high-temperature use, the tape may be carbonized and needs to be scraped off mechanically.
