3M Interam Endothermic Mat E-5A-4

3M Interam is a flexible mat with endothermic technology that releases chemically bound water to slow heat transfer and help protect critical electrical and structural components from fire when exposed to high temperatures or flame.

Non-flame supporting, low-smoke evolution and fast installation make this an excellent fire barrier for structural steel and electrical circuitry.
