Black Kapton Tape: High-Performance Insulation and Masking for Electronics and EV Batteries

What Is Black Kapton Tape?

Black Kapton Tape is a polyimide film tape coated with high-performance adhesive, offering outstanding thermal resistance, dielectric insulation, and chemical durability in demanding environments. Unlike standard amber Kapton tape, this version features a matte or glossy black finish, ideal for light-blocking, anti-reflection, and aesthetic masking applications.

It is widely used in electronics, aerospace, EV batteries, and flexible circuits, especially where discreet appearance or light shielding is required.

Key Features of Black Kapton Tape

• High Temperature Resistance: Operates reliably in temperatures up to 260°C (500°F), suitable for soldering, reflow, and insulation.
• Excellent Electrical Insulation: Provides superior dielectric performance in high-voltage environments such as PCB manufacturing and battery modules.
• Light-Blocking and Low Reflectivity: The black color is perfect for optical masking, sensor shielding, and applications where light control is critical.
• Chemical and Solvent Resistance: Performs in harsh environments including exposure to acids, oils, and solvents.
• Clean Adhesion and Removal: Leaves no residue, making it suitable for temporary masking and long-term installations.

Common Applications

• Lithium-ion battery wrapping and insulation in EV and BESS systems
• Light shielding in camera modules, sensors, and optical devices
• High-temp masking during PCB reflow or wave soldering
• Insulation of flexible circuits, motors, and transformers
• Die-cut black Kapton pieces for cleanroom and electronic subassemblies

Why Choose Black Over Amber Kapton Tape?

While both offer the same base properties of polyimide durability, the black version adds light absorption, minimal reflectivity, and cleaner aesthetics, making it ideal for optical, automotive interior, and consumer electronics markets. Custom Options Available
