Polyimide Tape with Silicone Adhesive – High-Temp Performance Guide

What is Polyimide Tape with Silicone Adhesive?

Polyimide tape with silicone adhesive (also known as silicone-backed Kapton tape) is a high-performance pressure-sensitive tape that combines polyimide film's extreme heat resistance with silicone adhesive's superior bonding properties. This specialized tape is engineered for applications requiring:

✔ Continuous exposure to 260°C (500°F) temperatures 
✔ Excellent electrical insulation (up to 7,200V dielectric strength) 
✔ Chemical resistance against solvents, acids, and oils 
✔ Clean removal without residue after high-temperature use 

The silicone adhesive formulation provides strong initial tack while maintaining performance across extreme temperature ranges (-73°C to 260°C), making it ideal for aerospace, electronics, and industrial manufacturing.

Key Advantages Over Standard Adhesives

1️⃣ Unmatched Thermal Stability

• Withstands repeated thermal cycling between -73°C to 260°C without degradation 

• Maintains adhesion during reflow soldering (260°C+) and wave soldering processes 

• Unlike acrylic adhesives, silicone doesn't char or carbonize at high temps 

2️⃣ Superior Electrical Properties

• Dielectric strength 6,000-7,200V (H-class insulation) 

• Low outgassing critical for vacuum applications (space/aerospace) 

• Flame retardant (UL94 V-0 rating) 

3️⃣ Chemical & Environmental Resistance

• Resists fuels, solvents, acids, and electrolytic fluids 

• UV and radiation stable - won't degrade in harsh environments 

• Moisture-resistant backing prevents electrical leakage 

4️⃣ Precision Performance

• Available in ultra-thin gauges (0.025mm-0.15mm) 

• Clean removal without adhesive transfer 

• Die-cuttable for custom shapes in automated assembly
