Anatomy of Quality

Multi-layer construction engineered for extreme performance and clean removal.

1. Polyimide Film
Designed to meet performance criteria comparable to UL 510
25µm / 50µm
2. Silicone Adhesive
Pressure Sensitive
25–35µm
3. Release Liner
PET / Fluorosilicone
Optional

Why Silicone Adhesive?

Unlike acrylic, silicone maintains bond strength at 260°C and removes cleanly without leaving sticky residue.
