3M™ Double-Coated Black PET Tape 55260B utilizes a black polyester film carrier coated with high-tack acrylic adhesive. With an optical density exceeding OD 4, it provides complete light-blocking performance for smartphone and tablet display panels while delivering outstanding drop-shock resistance.
Key Performance Highlights
- Black PET carrier delivers 100% optical light block with optical density OD > 4
- High-tack acrylic adhesive resists dynamic drop shock and shear stress
- PET carrier ensures razor-sharp precision die-cutting without fiber burrs
- Resists environmental moisture, thermal cycling, and skin cosmetic contact
Recommended Industrial Applications
Smartphone display panel attachment, bezel bonding, optical module sealing
