3M Interam Endothermic Mat

Product Description

3M Interam Endothermic Mat E5A4 chemically absorbs heat It releases chemically bound water that cools the outer surface of the mat when exposed to extreme heat

This helps decelerates temperature rise and slows heat transfer even during intense fires Developed to provide up to 4hour 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 rear and sides of metallic utility boxes this endothermic mat helps achieve an equal Frating and TRating in membrane penetrations of rated wall assemblies It also protects against large hydrocarbon pool fires in accordance with ASTM E 1529 UL 1709

Noncorrosive and requires no maintenance when properly installed

Versatile rated for structural steel electrical circuits wall opening membranes

Flexible easy to cut and configure for installation on complex shapes and around corners
