PI Polyimide Tape

PI Polyimide Tape: High-Performance Adhesive Solution for Thermal and Electrical Demands

PI Polyimide Tape is a specialty adhesive tape made from high-purity polyimide film coated with high-temperature-resistant silicone or acrylic adhesive. Designed for industrial, electronic, and aerospace environments, this tape excels in extreme conditions where conventional tapes degrade. It offers a superior balance of heat resistance, electrical insulation, dimensional stability, and chemical durability.

Key Features & Benefits

• Extreme Temperature Resistance:
  Operates continuously from -269°C to +260°C, withstanding short-term peaks up to 500°C, making it ideal for high-temperature masking, soldering, and insulation.

• Excellent Electrical Insulation:
  Dielectric strength up to 6.5 kV ensures safe and stable performance in circuit board protection, motor insulation, and coil winding.

• High Adhesion, No Residue:
  The silicone adhesive ensures strong bonding to metal, plastic, glass, and PCB surfaces, and removes cleanly without residue.

• Chemical & Solvent Resistance:
  Resists acids, bases, oils, and most organic solvents — essential for chemical processing, battery assembly, and semiconductor fabrication.

• Dimensional & Mechanical Stability:
  Maintains integrity under mechanical stress and thermal cycling, with low shrinkage and elongation at elevated temperatures.

• Anti-Static / ESD Options:
  Available in ESD-safe versions for cleanroom use and sensitive electronic assemblies.

• Flame Retardant & Low Outgassing:
  Compliant with UL94 V-0, RoHS, and REACH standards; suitable for vacuum systems, space-grade applications, and ISO Class 5 cleanrooms.

Applications

• PCB Masking & Wave Soldering: Temporary insulation during soldering, preventing thermal damage to adjacent components

• Electrical Coil and Transformer Wrapping: Insulation in motors, transformers, and magnetic components

• Lithium Battery Insulation & Wrapping: Safe high-temp insulation for battery tabs, modules, and separators

• 3D Printing & Heated Beds: High-adhesion surface for printing thermoplastics like PEEK, ABS, and Nylon

• Aerospace & Automotive: Wiring harnesses, connectors, thermal shielding, EMI protection
