FAQ (Frequently Asked Questions)
Q: How does polyimide tape compare to regular electrical tape?
A: Polyimide tape offers far higher temperature resistance (up to 400°C vs 80°C for PVC tape) and better chemical/electrical performance.
Q: Can it be used for lithium battery insulation?
A: Yes! It's ideal for Li-ion battery cell wrapping due to its heat resistance and flame retardancy.
Q: Does the adhesive melt under high heat?
A: No! The silicone adhesive remains stable even at 260°C+ (500°F).
Q: Is it reusable?
A: No, it's designed for single-use high-temp applications.
Q: What colors are available?
A: Standard amber (gold), also black (matte/gloss), and red for color-coding.
Q: Can it be laser-cut for custom shapes?
A: Yes! Polyimide film is precision-cuttable for specialized applications.
