When properly installed, 3M™ Interam™ Endothermic Mat E-5A-4 provides a uniform covering that, when exposed to high temperatures, releases chemically-bound water to cool the outer surfaces of the wrap material and significantly retard heat transfer. Helps protect structural steel, critical electrical and communication systems, fuel oil piping, and large membrane penetrations in walls.
3M™ Interam™ Endothermic Mat E-5A-4 is non-flame supporting with low-smoke evolution. The mat is flexible which aids in installation and allows it to more easily be applied on complex shapes and around corners.
- Up to 4-hour protection for structural steel (ASTM E119/UL 263 and ASTM E1725/UL 1709), up to 3-hour electrical circuit protection (ASTM E 1725) and up to 2-hour protection for wall opening membranes (UL 1479)
- Outstanding performance in high-intensity fires, provides protection against large hydrocarbon pool fires in accordance with ASTM E 1529 (UL 1709)
- Easy to cut and easy to install, flexible mat can even be installed directly over existing conduits fire protection
- Exterior durability when covered with 0.010 in. stainless steel jacketing
- Re-enterable for effective maintenance and inspection
