ESD Polyimide Tape
A specialized protective material for the electronics industry. It combines polyimide (PI) film’s high-temperature resistance/insulation with ESD functionality—shielding sensitive electronics from static damage while enduring harsh production environments.
Core Features and Advantages
- Extreme Thermal Endurance: Withstands continuous temps over 260°C(500°F), ideal for reflow soldering/high-heat scenes.
- ESD Protection: Dissipates static charges to guard delicate electronic components.
- Superior Electrical Insulation: Maintains strong dielectric strength, fit for PCB/battery tab insulation.
- High Durability: Resists chemicals, abrasion & tearing for long-term industrial reliability.
- Precision Design: Thin yet robust, suitable for delicate tasks like flexible circuit bonding.

Product Selling Points
1. Substrate + Dual-Effect Antistatic Protection
- PI substrate: Withstands 260℃ high temperatures, high insulation (dielectric strength ≥120kV/mm)
- Paired with antistatic coating/adhesive layer: Surface resistance 10⁶–10⁹Ω, peeling electrostatic voltage ≤50V; prevents ESD damage to chips/FPCs during unwinding/peeling
- Antistatic layer preserves PI’s chemical/radiation resistance & high mechanical strength; withstands harsh conditions (e.g., SMT reflow soldering) with long-term stable resistance
2. Precision Bonding + Residue-Free · Mass Production Compatible
- Uniform adhesive layer (controllable adhesion): Precisely bonds to PCB gold fingers/battery tabs; residue-free after removal (avoids contamination/short circuits)
- Supports die-cut customization + automated placement; achieves antistatic/insulation/shielding in one step, boosting efficiency & cutting costs
3. Extreme Environment Stability · High-End Application Compatible
- Stable performance across -50℃ to 260℃+; resistant to acids/alkalis/solvents/damp-heat aging (suitable for new energy batteries/avionics)
- Complies with RoHS/REACH standards; no corrosive ions, ensuring long-term product reliability
