Double Sided Polyimide Tape
Polyester double-sided high-temperature tape, also known as PET double-sided tape, is an industrial tape made from a transparent or colored polyester film (PET) backing, coated evenly on both sides with a high-performance pressure-sensitive adhesive (usually an acrylic adhesive), and then laminated with a release film (or release paper).
Features: 1. Excellent temperature resistance 2. High bond strength 3. Ultra-thin and conformable 4. Chemical and weather resistance
Applications: 1. Electronics assembly 2. Home appliance manufacturing 3. Automotive industry
Product Selling Points
- High-Temp Insulation Stability: PI substrate, double-sided 260℃ resistance + high insulation; stays reliable in extreme environments, suitable for reflow soldering/high-temp curing.
- Efficient Double-Sided Bonding: Precise uniform adhesive coating; single application bonds & protects two components simultaneously, boosting assembly efficiency.
- Residue-Free Protection: Double-sided no-residue design + PI’s chemical resistance; avoids precision surface contamination, fit for electronics/new energy high-end scenarios.
- Customizable Adaptability: Supports custom double-sided bonding (same/different adhesives); compatible with multiple substrates, PI’s high mechanical strength prevents edge lifting on complex curves.

Customizable styles
1. Polyimide CIRCLES
Primarily used for localized masking and protection in electronic manufacturing, such as:
- precise masking during PCB wave soldering and gold finger spraying (to prevent solder joints/gold fingers from being contaminated);
- protection of specific areas in high-temperature spraying processes (high temperature resistance, easy peeling, and no residue).
2. Polyimide rectangular
It belongs to the category of die-cut custom shapes and is commonly used for:
- fixing and insulating the positive/negative tabs of lithium batteries;
- component masking in SMT (Surface Mount Technology) processes;
- partial insulation wrapping of motor and transformer coils.
3. Polyimide Rolls
Supplied in roll form, suitable for large-area/continuous processing scenarios:
- Coil insulation wrapping for motors and transformers (resistant to high and low temperatures, high insulation level);
- Substrate for flexible printed circuits (FPC);
- High-temperature insulating sleeves for cables.
4. Polyimide Sheets
Suitable for large-area/custom-size insulation/substrate needs:
- Encapsulation substrates for high-temperature heating films (such as heating elements in aerospace/medical equipment);
- Sample support films for X-ray fluorescence spectroscopy (XRF) analysis;
- Structural support and overall protection of gold fingers for flexible circuit boards.
