Wide Industrial Application Scope of Brown Polyimide PI High Temperature Tape
Brown polyimide PI tape (Kapton tape) is a top-tier high-temperature industrial protective material with an ultra-high heat resistance limit up to 260℃ instant temperature. Equipped with excellent insulation, acid & alkali resistance, tear resistance and residue-free peeling, it is widely used in precision electronics, new energy lithium batteries, semiconductor manufacturing, high-temperature spraying and aerospace precision processing, covering all extreme high-temperature working scenarios that ordinary PET tape cannot bear.
1. Electronics, PCB & Semiconductor Industry
This is the core largest application field of brown PI tape.
• Cover PCB gold fingers during reflow soldering, wave soldering to block solder splashes
• Temporary masking for FPC flexible circuit board high-temperature processing
• Insulation wrapping for transformers, coils, magnetic rings and fine wire harnesses
• High-temperature protection for chip packaging, wafer cutting and semiconductor testing
• No glue transfer after long-time baking, no corrosion on precision circuit and chip surfaces
2. New Energy Lithium Battery & Energy Storage
PI tape is a mandatory insulation material for lithium battery production due to its ultra-high heat resistance and flame retardancy.
• Insulate positive & negative lugs of lithium batteries to prevent short circuit
• Isolate internal cells of battery packs and energy storage modules
• Fix electrode sheets during high-temperature coating and rolling process
• Heat insulation protection for battery management system (BMS) components
• Pass flame retardant and RoHS certification, safe for new energy automatic production lines
3. Hardware High-Temp Spraying, Powder Coating & Curing
For workpieces requiring ultra-high temperature baking above 200℃ that PET tape cannot withstand.
• Mask reserved assembly holes and threaded positions during high-temperature powder coating
• Stable under 230–260℃ long baking without melting, shrinkage or glue oozing
• Produce clean straight masking lines, easy to peel off with zero residual glue
• Mainly used for auto metal parts, high-end aluminum alloy, precision mold spraying
4. Aluminum Alloy Anodizing & Hard Electroplating
PI film features outstanding resistance to strong acid, strong alkali and long chemical soaking.
• Shield precision threads, assembly surfaces during hard anodizing and electroplating
• Resist pickling liquid, oxidation dye, heavy metal plating solution without liquid penetration
• No edge lifting even after dozens of minutes of tank soaking
• Ideal for mobile phone frames, camera aluminum parts, precision hardware accessories
5. Automotive & Aerospace Precision Manufacturing
Aerospace and auto core components face extreme temperature changes during production and service.
• High-temperature masking for engine metal parts spraying and curing
• Insulation wrapping for new energy vehicle high-voltage wiring harness
• Heat isolation protection for aerospace sensor and precision alloy parts
• Anti-aging, anti-corrosion, stable performance under long-term high-low temperature cycles
6. Plastic Injection Molding & High-Temp Die Casting
• Mask plastic precision positioning holes during high-temperature secondary spraying
• Isolate molten metal during die casting to avoid workpiece scratch
• Withstand instantaneous high temperature during injection molding demolding process
• No glue residue to damage plastic glossy surfaces
7. 3C Optical & Precision Instrument Industry
• Local protection for camera lenses, glass optical parts during high-temperature coating
• Temporary fixing for precision instruments in high-temperature aging test
• Anti-static insulation protection for micro precision electronic accessories
