Acrylic polyimide tape
One-side coated with silicone-free acrylic PSA on a PI film, then laminated and slit. Core value: solves silicone contamination from silicone PI tape, ideal for precision electronic processes and high-temp clean masking. A key auxiliary material for PCBs, semiconductors, FPCs, etc.
- Strong, Versatile Adhesion: Bonds well to metals, plastics, glass; long-lasting strength with shear/aging resistance.
- Temp & Weather Durability: -60℃~175℃ (short-term 260℃); UV, humidity, and heat resistant for stable performance.
- Clean, Low Contamination: Silicone-free (selected models); low outgassing/ions; residue-free peeling for clean electronic processes.
- Reliable Insulation: H-class insulation with high dielectric strength and volume resistivity for safe electrical isolation.
- Chemical Resistance: Withstands weak acids/bases, alcohol, and common solvents; suitable for chemical masking/corrosion protection.
- Process-Friendly: Easy to die-cut/apply; compatible with automated lines to boost efficiency.

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.
