High Temperature Polyimide Tape – 260°C Heat Resistant, Electrical Insulation & PCB Masking For Soldering

PI tape (Polyimide tape) is made of a high-temperature resistant polyimide film backing coated with high-performance silicone adhesive. It offers excellent electrical insulation and heat resistance. Widely used in electronics manufacturing, high-temperature masking, and lithium-ion battery tab fixing, it is a critical auxiliary material in precision industrial processes. Its operating temperature typically ranges from -70°C to 260°C, with the ability to withstand even higher temperatures for short periods.

Technical Specifications
Material Polyimide Film
Adhesive Type Pressure Sensitive Silicone Adhesive
Thickness 30um~100um
Key Advantages
  • Extreme High-Temperature Resistance: Withstands long-term exposure to 260°C and short-term spikes above 300°C without melting, deforming, or leaving residue—ideal for reflow and wave soldering processes.
  • Strong Insulation & Chemical Resistance: Features a breakdown voltage of over 5kV and resists acids, alkalis, radiation, and solvents, effectively protecting sensitive electronic components.
  • Conformable & Residue-Free Removal: The adhesive offers balanced tack, leaving no residue or contamination after peeling. The flexible backing conforms easily to curved or irregular surfaces.
Primary Applications
  • High-Temperature PCB Protection: Masks gold fingers, connectors, and slots on circuit boards during reflow or wave soldering to prevent solder contamination or high-temperature oxidation.
  • Lithium Battery Tab Fixing: Secures and insulates tabs during cell manufacturing, resisting electrolyte exposure and subsequent high-temperature formation processes.
  • High-Temperature Spray Masking: Provides local protection for electronic components, motor coils, or automotive parts during high-temperature sandblasting, painting, or powder coating.
