he 3M™ Interam™ Endothermic Mat E-5A-4 is composed of a combination of materials, including ceramic fibers and inorganic endothermic material. In the event of fire, they help prevent heat penetration via a chemical reaction that absorbs heat energy.

The 3M™ Interam™ Endothermic Mat is non-flame supporting and offers low smoke evolution, making it an excellent fire barrier for structural steel and electrical circuitry. This mat is composed of a combination of organic and inorganic materials, and includes an aluminum backing. These advanced endothermic materials contain chemically bound water, helping to prevent heat penetration via a chemical reaction which absorbs heat energy. The endothermic mat blocks heat penetration by chemically absorbing heat energy to protect structural steel, cable trays and circuits in conduits. It can provide up to 4 hours of protection for structural steel and up to 3 hours of electrical circuit protection. The Interam endothermic mat meets the following ASTM (UL) and NBN/ISO Standard Test Requirements: ASTM E 84 (UL 723) Surface Burning Characteristics of Building Materials, ASTM E 119 (UL 263) Fire Tests of Building Construction and Materials, ASTM E 1529 (UL 1709) Determining Effects of Large Hydrocarbon Pool Fires on Structural Members and Assemblies, ASTM E 1725 Fire Tests of Fire-Resistive Barrier Systems for Electrical System Components and NBN 713-20/ISO TC 92 Simulated Jet-Fire Test.

  • Fast and easy installation
  • Non-flame supporting
  • Low smoke evolution
  • Endothermic materials contain chemically bound water
  • Flexible for wrapping around corners and obstacles
