Category Overview
Heat Resistant Insulation Tape is used where heat, electrical separation, adhesive stability, and surface cleanliness must be controlled together. A practical specification should not stop at maximum temperature or roll width. Teams usually check backing thickness, adhesive thickness, total thickness, dielectric breakdown, insulation resistance, residue after heating, and thermal aging behavior.
Thin PI and PET films help insulation stay flat. Fiberglass cloth adds tensile strength for coil or transformer work. Acetate cloth gives softer wrapping and varnish absorption. PTFE-based tapes are used on heated metal surfaces where non-stick release and low friction are required.
Product Range / Covered Products
| Product Series | Main Structure | Typical Use Boundary |
|---|---|---|
| PI Film Insulation | PI film, silicone or acrylic adhesive | PCB, SMT, FPC, battery, thin motor insulation |
| PET Polyester Insulation | PET or Mylar-type film | Medium-temperature insulation, transformer layers |
| Fiberglass Cloth Insulation | Woven fiberglass cloth | Motor coil, transformer, abrasion areas |
| Acetate Cloth Wrapping | Acetate cloth, rubber resin or acrylic adhesive | Flexible coil wrapping, varnish absorption |
| ESD Polyester Process | Static-dissipative polyester film | Static-sensitive PCB, FPC, semiconductor processing |
| PTFE Release Insulation | PTFE film or PTFE glass cloth | Sealing jaws, heat sealing bars, release surfaces |
For PCB, SMT, and FPC work, electrical insulation polyimide tape is selected when a thin, stable, high-temperature film is required. High temperature polyester tape is better for medium-temperature insulation where flatness matters. Fiberglass cloth insulation tape fits heat plus pull or abrasion. Acetate cloth insulating tape is better for flexible coil wrapping where conformability and varnish compatibility matter.
Selection Guide
Start with working condition, material, and adhesive. For PCB/FPC, confirm peak temperature, dwell time, solder exposure, removal timing, and residue tolerance. For coil and transformer insulation, confirm winding tension, edge lift, varnish absorption, dielectric need, and heat aging. For heat sealing equipment, confirm heated metal surface, friction, adhesive holding, and replacement cycle.
| Material / Glue Choice | Strengths | Check Before Bulk Use |
|---|---|---|
| PI + silicone | High heat, dielectric stability, clean removal | Silicone transfer, residue, shrinkage |
| PI + acrylic | For silicone-sensitive processes | Lower heat margin |
| PET + acrylic | Thin, economical film insulation | Heat limit, adhesive softening |
| Fiberglass cloth + silicone | Heat, tensile, abrasion resistance | Edge fray, adhesive flow |
| Acetate cloth + rubber resin | Conformable, hand tearable, varnish-friendly | Temperature class, edge lift |
| PTFE glass cloth + silicone | Non-stick, low friction, chemical resistance | Metal adhesion, wear life |
Avoid approving a tape only by its highest temperature. PET near reflow may soften or leave residue. Thick fiberglass cloth may be too stiff for small die-cut pads. PTFE works well on sealing jaws, but not for tight coil wrapping.
Benefits
· Matches material structure to real heat, insulation, and process conditions
· Supports thin electronic insulation, fabric coil wrapping, static-sensitive processing, and heated release surfaces
· Allows dielectric breakdown, insulation resistance, heat aging, and residue checks before scale-up
· Available as log rolls, slit rolls, sheets, liner-backed parts, kiss-cut parts, and die-cut pads
What Technical Data Should Be Checked Before Slitting or Die-Cutting Heat Resistant Insulation Tape?
Before slitting or die-cutting, check more than width and thickness. For PCB, SMT, FPC, motor coil, transformer, and heat sealing projects, confirm backing thickness, adhesive thickness, total thickness, dielectric breakdown, insulation resistance, adhesive type, heat aging behavior, and release liner structure. Thin PI and PET films help the insulation layer stay flat. Glass cloth and PTFE glass cloth need review of edge fray, adhesive flow, cut-edge cleanliness, liner release force, and residue after heat exposure.

· FPC processing, flexible circuit protection, small die-cut pads, and local insulation points
· Motor coil wrapping, transformer layer insulation, end-winding support, and lead connection insulation
· Heat sealing equipment, sealing jaws, heat-sealing wires, bag sealing, and release surface protection
Customization Options
High TempTapes Company can adjust backing type, adhesive system, thickness, width, length, color, liner, and converted shape. For roll products, confirm usable width, core size, adhesive side, unwind behavior, and clean removal after heat exposure.
For die-cut parts, drawings should define outside size, hole position, corner radius, liner type, part spacing, and tolerance. Sample checks may include residue after heat, edge lift, adhesive transfer, varnish compatibility, and insulation data after thermal aging.
How Should Each Material Be Matched to the Working Temperature and Insulation Risk?
Material selection should start from the real process condition, not only the highest temperature on a data sheet. PI film is stronger for PCB solder protection, FPC processing, and thin motor insulation where dimensional stability and dielectric performance matter. PET polyester tape fits medium-temperature insulation and cost-sensitive assemblies. Fiberglass cloth tape is better when heat is combined with mechanical stress. Acetate cloth tape fits flexible coil wrapping where conformability and varnish absorption matter. PTFE or PTFE glass cloth tape should be kept for non-stick release surfaces and sealing bars rather than general coil insulation.
FAQ
How do I choose between PI, PET, fiberglass cloth, acetate cloth, and PTFE tape?
Choose PI for thin high-temperature insulation, PET for medium-temperature film insulation, fiberglass cloth for heat plus strength, acetate cloth for flexible coil wrapping, and PTFE for non-stick heat sealing surfaces.
Can Heat Resistant Insulation Tape be supplied as die-cut parts?
Yes. It can be supplied as slit rolls, sheets, pads, strips, and kiss-cut parts. Confirm tolerance, liner type, edge quality, hole position, and heat exposure.
What data should be confirmed before procurement?
Confirm backing material, adhesive thickness, total thickness, temperature exposure, dielectric breakdown, insulation resistance, residue after heat, roll size, liner type, and temporary or permanent use.
What heat aging details should be checked before approval?
Check edge lift, shrinkage, discoloration, residue, adhesive transfer, dielectric retention, and flatness after actual temperature and dwell time.
