Key Roles of High-Temp Tape
- Its base material (such as polyimide) has high temperature resistance (usually withstanding 200-500°C), which can endure high-temperature processes in capacitor production, such as welding and curing.
- Its adhesive layer has both insulation and adhesion properties. It can not only insulate current to prevent short circuits, but also fix components stably without falling off or producing harmful substances in subsequent processes or use, thus ensuring the performance and service life of capacitors.
Comprehensive Solution
PI tape is mainly used in solid-state capacitors and supercapacitors for: insulation protection (of leads, plates, and casings), high-temperature process protection (during reflow soldering and welding), and fixation and mechanical reinforcement (for cell winding and module assembly). It is one of the key materials for ensuring the reliability and lifespan of capacitors
In aluminum electrolytic capacitors, polypropylene tapeis mainly used for:
Winding fixation (ensuring core stability)
Insulation protection (electrodes, casing, leads)
Module separation (multi-capacitor assemblies)
It is an indispensable insulating and fixing material in capacitor manufacturing.
Why does the capacitor industry choose PI tape as the main functional electronic auxiliary material?
High temperature resistance: withstands short-term temperatures ≥260 °C, suitable for reflow soldering processes.
Excellent electrical insulation: high dielectric strength ensures safe operation of capacitors
Chemical resistance: resists the effects of electrolytes and solvents.
High mechanical strength: protects the structural stability of the capacitor.
