Interam™ Endothermic Mat E-5A Series
Flexible Wrap for Industrial Fire Protection
Applications
Electrical & Control Systems
When a fire occurs, the electrical systems that control critical areas such as control rooms, ventilation, lighting, alarms and elevators must remain operational in order to facilitate a safe and orderly plant shutdown and evacuation. With 3M™ Interam™ Brand E-Mat (Endothermic Mat), cable raceways, conduit, equipment shrouds and other electrical control systems can be protected for up to three hours in intense heat.
3M™ Interam™ Brand E-Mat is significantly more flexible and conformable than traditional rigid panel systems. So it’s easier to install on the complex shapes common in electrical systems. Installation is quick and clean, and can be accomplished by a trained crew.
3M™ Interam™ Brand E-Mat Flexible Endothermic Wrap offers more than thermal insulation. These advanced endothermic materials contain chemically bound water. In the event of fire, they help prevent heat penetration via a chemical reaction which absorbs heat energy. And because 3M™ Interam™ Brand E-Mat Flexible Wrap provides flexible, full envelope protection for electrical cabling, structural steel and pipelines, you can be assured of protection when and where it’s needed most.

Structural Steel
Leaving structural steel exposed to fire can lead to irreparable damage of a facility’s superstructure, thus compromising continuity of operations. 3M™ Interam™ Brand E-Mat Flexible Wrap provides an easy solution.
Traditionally, structural steel has been protected with messy, sprayed on materials or encased in concrete. 3M™ Interam™ Brand Endothermic System can reduce the amount of time to install structural steel fireproofing from 25-40 percent. It doesn’t spall, crack or chip. It won’t corrode steel or other metals. Whether used for retrofit or new construction, the system’s flexibility allows it to be installed easily and maintained with virtually no disruption to surrounding areas.

Pipelines & Valves
When you’ve got a fire on your hands, the last thing you want to do is feed it fuel through a ruptured pipeline. A great way to help protect pipelines from ruptures caused by fire is to use 3M™ Interam™ Brand E-Mat Flexible Wrap.
3M™ Interam™ Brand E-Mat can be easily applied to insulated steam lines, pipelines and valves containing combustible or dangerous liquids and gases. The flexible material provides an envelope of endothermic protection surrounding the entire length of pipe. 3M™ Interam™ Brand E-Mat Flexible Wrap can also be easily removed in order to inspect lines for corrosion
