3M™ Interam™ E-5A-4 Endothermic Mat 24-1/2" x 20' 3 Mil Silver 7000031969
3M™ Interam™ E-5A-4 Endothermic Mat 24-1/2" x 20' 3 Mil Silver
The 3M Interam Endothermic Mat E-5A-4 is a heat-absorbing wrap system that provides excellent fire resistance for critical structural steel, electrical components, and wall opening membranes. It releases chemically-bound water to cool its outer surfaces when exposed to intense heat, reducing temperature rise and slowing heat transfer. This flexible mat is easy to cut and configure for complex installations, offering up to 4-hour fire protection for structural steel applications and 3-hour protection for electrical circuit applications. Recommended for use on structural steel, electrical circuitry, membrane penetrations, and equipment shrouds, it provides non-corrosive, maintenance-free fire protection.
Top product features:
- Provides protection against intense fires including hydrocarbon pool fires
- Releases cooling chemical-bound water when exposed to extreme heat
- Blocks heat by chemically absorbing it, reducing the rate of temperature rise and slowing heat transfer
Top product applications:
- Structural steel
- Electrical circuits/raceways
- Membrane penetrations (e.g. spaces containing electrical panels, elevators, etc.)
This item is NOT returnable.
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. Highlights ul style"margin-top0px; padding-top 5px; padding-bottom 5px;" 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 a cool system for fire protection tested for a full range of critical applications our 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. This mat 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 and when applied to the back and sides of metallic utility boxes our endothermic mat helps achieve an equal f-rating and t-rating in membrane penetrations of rated wall assemblies. It also protects against large hydrocarbon pool fires in accordance with astm e 1529 (ul 1709).
