Acrylic Polyimide Tape (K-610)
Acrylic Polyimide Tape (Kapton®-Type PI Film Tape with Acrylic PSA)
High-Temperature Masking & Electrical Insulation for PCB, Coils, Motors and Converting
Our Acrylic Polyimide Tape is made from polyimide (PI) film coated with a high-performance acrylic pressure-sensitive adhesive (PSA). It delivers reliable bonding,strong shear performance and stable insulation properties for demanding manufacturing processes such as electronics assembly,motor/transformer insulation, and high-temperature masking.

We also supply silicone adhesive grades separately. Contact us for the correct product recommendation and TDS.
Key Features & Benefits
Acrylic PSA for reliable tack and shear holding on many industrial substrates
Heat resistance for production environments (Continuous temperature rating up to 155°C)
Polyimide film backing with excellent mechanical strength and electrical insulation
Chemical and solvent resistance typical of PI film masking applications (compatibility depends on chemical type, concentration, and exposure conditions)
Converting-friendly: available in rolls, sheets, and die-cut parts for automated assembly
Color options: standard amber/brown; black option available for light-blocking applications (upon request)
Applications
Acrylic Polyimide Tape is a practical non-silicone option for applications where silicone contamination should be minimized. It combines the heat resistance and electrical insulation of polyimide film with the stable bonding performance of an acrylic pressure-sensitive adhesive.
Electronics Assembly & PCB Manufacturing (Silicone-Free)
- Wave Solder Masking: Used for high-temperature masking in PCB manufacturing, including gold finger and selected contact-area protection.
- Process Protection in Non-Silicone Environments: A suitable option for selected electronics assembly processes where silicone contamination is a concern.
- Fine Wire and Lead Fixing: Helps secure fine wires, leads, or insulation layers in compact electronic assemblies.
EV & Lithium-ion Battery Insulation
- Cell and Tab Insulation: Used in selected battery-pack and cell-assembly applications for electrical insulation, edge protection, and part fixing.
- Sensor or Material Fixing: Can be used to secure selected insulating materials, sensors, or components where a non-silicone adhesive system is preferred.
- Process Validation Recommended: Chemical compatibility should always be confirmed against the actual electrolyte system, dwell conditions, and substrate materials.
Electrical Insulation (Motors, Transformers & Coils)
- Class F (155°C) Insulation: High-performance insulation for lead wire reinforcement, phase insulation, and coil end-turns.
- Varnish & Resin Compatibility: Exceptional resistance to impregnating resins and cleaning solvents used in motor manufacturing, ensuring the tape doesn’t soften or flag during the baking cycle.
- Transformer Core Wrapping: Securely holding copper foils and insulation layers in high-frequency transformers.
Acrylic Kapton tape is suitable for insulation layer fixing, component protection, battery module insulation support, and busbar area protection where stable adhesion and polyimide film performance are required.
