This blanket has been known to be flexible enough to cover compound curves. The heat side of the blanket is covered with stainless steel, the other side is aluminum It is easy to rivet or can be glued into position. Sold by the running foot. Temp. range up to 1000F. 24 inch wide.
When properly installed, 3M™ Interam™ Endothermic Mat E-5A-4 provides a uniform covering that, when exposed to high temperatures, releases chemically-bound water to cool the outer surfaces of the wrap material and significantly retard heat transfer. Helps protect structural steel components for up to four hours, critical electrical components for up to three hours and wall opening membranes for up to two hours. Applied to the back and sides of metallic utility boxes, this product helps achieve an equal F-Rating and T-Rating in membrane penetrations of rated wall assemblies. 3M™ Interam™ Endothermic Mat E-5A-4 is non-flame supporting with low-smoke evolution. The mat is flexible which aids in installation and allows it to more easily be applied on complex shapes and around corners.
Note: There is a stainless steel sheet glued on to one side for extra protection. Tech Data Sheet does not include any info on this extra steel sheet.

Customer Service Manager went the distance to resolve the previous issues with crumpled & partial missing stainless steel covering on the 3M firewall composite material. She is to be commended for her professional and courteous approach to your customers. Pilots and homebuilders can source their materials & parts from many options... but this kind and considerate approach is what keeps us coming back to Aircraft Spruce & Specialty.
