E&H 743-BLK Black PVF Insulation Blanket Cover Splicing Tape | FAR 25.856(A) | FAR 25.853 | BSS-7230 | Tedlar Film

Please Note: All E&H products have a 1-2 weeks lead time

The aerospace industry's specialized insulation blanket cover splicing tape — engineered for the fabrication and installation of aircraft thermal insulation blankets where fire retardance and durability are mandatory. Used by insulation blanket manufacturers, MRO shops, and airline maintenance teams to seal sewn seams, close fabrication slits, and cover holes around brackets and conduits in aircraft interior installations. E&H 743-BLK is a black polyvinyl fluoride (PVF/Tedlar) film tape with a 10x10 visual scrim reinforcement and a highly fire-retardant acrylic pressure-sensitive adhesive. Manufactured by E&H Laminating & Slitting Company — the recognized specialist in aircraft insulation blanket tapes — it passes the FAA Critical Radiant Heat Panel test, FAR Part 25.856(A), FAR Part 25.853 (A or B), and the BSS-7230 12-second vertical burn test. Flame time is 0 seconds with no drips, making it one of the most stringent fire-performance tapes in the insulation blanket market. Shelf life is a minimum of 18 months in cool, dry storage.
