3M Interam Endothermic Mat E-5A-4
Description

3M Interam™ Endothermic Mat E-5A-4 is an easy-to-install heat-absorbing wrap system that provides excellent fire resistance for structural steel components, critical electrical components, and wall opening membranes. When exposed to intense heat, the mat releases chemically-bound water to cool its outer surfaces. Installers can easily cut the material to fit even complex installations.

A Cool System for Fire Protection tested for a full range of critical applications, 3M Interam Endothermic Mat E-5A-4 blocks heat by chemically absorbing it — when exposed to extreme heat, it releases chemically bound water that cools the outer surface of the mat. This helps reduce the rate of temperature rise and slows heat transfer even during intense fires.

Key Features
  • Provides protection against intense fires including hydrocarbon pool fires
  • Endothermic design releases cooling chemical-bound water when exposed to extreme heat
  • Versatile — rated for structural steel, electrical circuits, wall opening membranes
  • Flexible — easy to cut and configure for installation on complex shapes and around corners
  • Non-corrosive and requires no maintenance when properly installed
Scope of Use
  • Structural steel electrical circuity/raceways cables, cable trays and conduits
  • Equipment shrouds membrane penetrations (e.g. spaces containing electrical panels, elevator call boxes, safe deposit boxes, medical gas boxes)
  • Critical systems for safe shutdown or occupant evacuation new or retrofit construction
  • Re-enterable for inspections

Installation:

  • 3M Interam Endothermic Mat E-5A arrives in a convenient roll that makes for simple storage and ease of use on the job site
  • Flexible and easy to cut and configure, this material makes installation faster and easier even on complex shapes and around corners 
  • There is no need for water, mixing or measurement to achieve specific thicknesses
  • Re-enterable and easy to inspect — simply unwrap the mat, inspect the component and re-wrap.
Statement of Building Code Compliance
  • Provides up to 4 hour fire protection for structural steel applications in accordance with ASTM E 119, up to 3 hour fire protection for electrical circuit applications in accordance with ASTM E 1725
  • When applied to the back and sides of metallic utility boxes, 3M's endothermic mat helps achieve an equal F-rating and T-Rating in membrane penetrations of rated wall assemblies
  • Also protects against large hydrocarbon pool fires in accordance with ASTM E 1529 (UL 1709)
Other Performance Attributes
  • The mat is available with stainless steel or aluminium backing and is non-corrosive, easy to clean and requires no maintenance when properly installed
