Polyimide Tape
Polyimide tape—often known by the brand name Kapton® tape—is a high-performance adhesive tape used across electronics, aerospace, automotive, and industrial manufacturing due to its thermal stability, electrical insulation, and chemical resistance.
Key Features of Polyimide Tape
-
Temperature Resistance: Operates from –269°C to +260°C.
-
Electrical Insulation: High dielectric strength ideal for PCB and transformer insulation.
-
Chemical Resistance: Resists acids, oils, solvents, and bases.
-
Flame Retardant: UL 94 V-0 rated options available.
-
Dimensional Stability: Maintains shape and performance under extreme conditions.
-
Clean Removal: Leaves no residue, making it excellent for masking.

Applications of Polyimide Tape
Used for masking during wave soldering and reflow processes, protecting PCB components from heat and flux.
High-Temperature Masking
Ideal for powder coating, anodizing, and plasma spraying, thanks to its resistance to extreme heat and chemicals.
Provides high dielectric strength for insulating wires, transformers, motors, and coils in high-voltage environments.
Aerospace & Automotive Applications
Polyimide tape performs reliably in harsh environments, making it suitable for insulation, sensor protection, and thermal shielding in aerospace and automotive systems.
Questions
Frequently Asked Questions
Is polyimide tape heat resistant?
Yes, it can typically withstand temperatures up to 300°C (572°F).
Can you use polyimide tape for powder coating?
Absolutely. It’s ideal for masking during high-temperature curing processes.
Does polyimide tape conduct electricity?
Most of the polyimide tape it is an excellent electrical insulator. Our aluminum polyimide tape and black polyimide can abe made to be conductive.
Will polyimide tape leave residue?
Silicone adhesive polyimide tape leaves no residue after removal.
Is Kapton the same as polyimide tape?
Kapton is a type of polyimide tape, specifically from DuPont. Many other brands provide equivalent performance.
