3M™ Matte Black Polyester Film Tape 1388B-1M is a specialty electrical tape with an anti-reflective matte black polyester backing and an acrylic adhesive. Its non-glare surface and high opacity make it the preferred solution for masking optical camera modules, display backlights, and electronic assemblies requiring anti-reflective black insulation.
Key Performance Highlights
- Matte non-reflective black surface eliminates internal optical glare and reflections
- Uniform light opacity prevents stray light leakage in display backlights and cameras
- High-tack acrylic adhesive bonds cleanly without adhesive ooze or flagging
- UL Recognized Class 130°C component for precision electro-optical hardware
Recommended Industrial Applications
Anti-glare optical light masking, camera module shielding, matte black transformer wrapping
