Scientific indicators for purchasing
Substrate thickness: Too thin and easy to tear, too thick affects flexibility
Adhesive type: Silicone adhesive has a higher temperature resistance than acrylic adhesive, but the initial adhesion is lower (ASTM D3330 peel force test)
Voltage resistance level: Select according to the application voltage (such as 6kV/mm for less than 1kV, and customization is required for more than 10kV)
Certification standards: UL certification (flammability), RoHS 2.0 (no harmful substances), ISO 9001 (quality management system), all three certificates are preferred
Surface treatment: Single-sided/double-sided conductive treatment (resistance value <0.1Ω/sq) to meet EMI shielding requirements, select according to electromagnetic compatibility requirements

Industry trends and technological innovations
Functional composite: Thermally conductive polyimide tape with integrated thermal conductive fillers (such as boron nitride) solves the heat dissipation problem of 5G chips.
Intelligent cutting: Laser pre-cut tape (accuracy ±0.1mm), adapted to the needs of automated mounting production lines.

Polyimide high-temperature masking tape has become the "invisible guardian" of the high-end manufacturing industry with its irreplaceable high-temperature resistance and insulation performance. When choosing, it is necessary to combine the actual working temperature, media compatibility, and certification requirements, and give priority to suppliers with transparent technical data and customized service capabilities.
