Polyimide tape is a specialized high-temperature resistant tape, often known by the brand name Kapton™-6-8. Its core strength is maintaining performance in extreme environments-6.
Here is a summary of its key characteristics and typical applications:
| Feature/Application | Details |
|---|---|
| ???? Key Characteristics | |
| High Temperature Resistance | Continuous use up to 260°C (500°F)-1-4-10; short-term exposure up to 371°C (700°F)-1 or 400°C-3. |
| Clean Removability | Silicone adhesive is designed to peel off without leaving residue after high-temperature exposure-1-2-5. |
| Other Properties | Excellent electrical insulation, chemical & flame resistance, dimensional stability-2-6. |
| ???? Common Applications | |
| Electronics Manufacturing | PCB solder masking, protecting components during wave/reflow soldering-2-4-7. |
| Industrial Masking | Masking for powder coating, e-coating, anodizing, and plasma spraying-1-4-6. |
| Aerospace & Automotive | Wire harness insulation, thermal protection in high-stress environments-6-8. |
| 3D Printing & Prototyping | Used as a build surface for certain materials due to heat resistance and adhesion-3-8. |
???? How to Choose the Right Tape
Beyond core features, your selection should be based on specific needs:
Adhesive Type: Most use silicone adhesive for clean removal-6-8. For stronger initial tack or specific substrates, acrylic adhesive tapes (like 3M™ 7421) are also available-6-9.
Tape Format & Size: It's available in rolls (various widths from a few mm to 300mm)-5-10, sheets, and pre-cut discs or shapes-1-6.
Special Features: For sensitive electronics, look for low-static or anti-static versions to prevent electrostatic discharge-10. For structural needs, reinforced versions with materials like fiberglass exist. https://store.unigulfsupply.com/product/high-temperature-polyimide-tape-20mm/
