3M™ lnteram 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 components for up to four hours, critical electrical components for up to three hours and wall opening membranes for up to two hours.
Applied to the back and sides of metallic utility boxes, this product helps achieve an equal F-rating and T-Rating in membrane penetrations of rated wall assemblies.
3M™ lnteram 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.
• Provides up to 4 hour fire protection for structural steel applications in accordance with ASTM E 119. • Provides up to 3 hour fire protection for electrical circuit applications in accordance with ASTM E 725. • Provides protection against large hydrocarbon pool fires in accordance with ASTM E 1529 (UL 1709]. • Chemically-bound water helps cool protective item(s] in the event of a fire. • Non-flame supporting • Low-smoke evolution • Flexible - can be installed on complex shapes and around corners • Easy-to-cut for various shapes and sizes • Non-corrosive • For use in new or retrofit applications • Easy to clean
3M™ lnteram Endothermic Mat E-5A-4 is a flexible and space-saving wrap system that protects against fire spread and smoke contamination in a wide range of new or retrofit applications requiring full envelope protection, including: structural steel, electrical circuitry I raceways, cables, cable trays, conduits, equipment shrouds, steam lines and membrane penetrations (e.g. spaces containing electrical panels, elevator call boxes, safe deposit boxes, medical gas boxes].
