0.05mm Polyimide Double Sided Kapton Tape | High Temp Die-Cut Manufacturer
0.05mm Polyimide Double Sided Kapton Tape | High Temp Die-Cut Manufacturer
Model Code
Model 2550
Total Thickness
0.05mm (50μm)
Base Carrier
Polyimide Film (Kapton)
Adhesive Type
Dual Silicone Coating
Engineered for High-Precision Thermal Bonding
The Model 2550 Double-Sided Kapton Polyimide Tape is engineered specifically for electronics manufacturing processes demanding extreme temperature endurance and ultra-thin profile integration. Featuring a total thickness of just 0.05mm (50 microns), this tape delivers exceptional dimensional stability and high dielectric strength without adding unnecessary stack-up height.
Coated with high-grade cross-linked silicone adhesive on both sides of a 0.025mm Amber Polyimide film, Model 2550 maintains steady bonding shear strength under continuous operational temperatures up to 260°C (500°F) and short-term thermal peaks up to 300°C.

Q: Does Model 2550 leave adhesive residue upon high-temperature removal?
A: No. Model 2550 utilizes a specially formulated cross-linked silicone adhesive that cleanly peels off from metal, glass, and PCB substrates without leaving silicone oil or sticky residue, even after exposure to 260°C reflow temperatures.
Q: Can you supply this tape in custom die-cut geometric shapes?
A: Yes, we provide full precision die-cutting services according to your CAD or PDF drawings. We can apply single or extended release liners (finger-lift) to facilitate automated assembly.
Q: How does 0.05mm thickness compare with standard 0.1mm double-sided Kapton tape?
A: At 0.05mm (50μm), Model 2550 provides half the profile height of traditional 0.1mm tapes, making it ideal for micro-electronics where thermal conductivity needs to be maximized across tight clearances.
Q: What is the lead time for B2B master rolls and custom width slitting?
A: Standard slitting widths (from 3mm up to 500mm) are shipped within 3–5 business days. Die-cut prototype samples can be prepared in as fast as 48 hours.
