3M™ Interam™ Mat I-10/I-10A Page 1 of 4 Technical Data Sheet September / 2019 Product Description 3M™ Interam™ Mat I-10/I-10A is a ceramic fiber-based material that expands into a low-density insulation blankets when ex posed to high temperatures or flames. These mats are used to protect against fire and to act as high temperature sealing mechanisms. The mat can be easily wrapped around complex shapes and surfaces. This feature allows them to be easily incorporated in to various fire protection systems such as electrical raceway fire-breaks and fire rate d roofing systems. Exposure to fire will cause intumescence or expansion, thus f illing openings to block the movement of flames and retard the transfer of heat. The intumescent characteristic of the material offers another unique opportunity for using the mats as a high temperature sealing or mounting device. As a sealant and gasketing material, systems ca n be engineered to have the mat expand and fill a desired area. The mat’s pressure of expansion can also be used to hold devices in place. The Interam™ Mat I-10/I-10A is lightweight, flexible and easily cut to the desired size and shape. Custom die cut parts are available to simplify installation of gaskets or other uniquely shaped components. Product Features  Expands only in thickness direction  Non-flame supporting  Allows heat dissipation in unexpanded state  Inhibits heat transfer when expanded  Lightweight and flexible  Easily cut to desired size and shape  Economical and easy to install — no surface preparation required Applications  Electrical circuit protection  Cable tray fire-breaks  Junction box protection  Expansion joints  High temperature gasketing  Fire rated roofing systems  Fire and smoke protection in OEM applications

For a typical mat installation, the following tools may be of assistance: razor knife or large scissors (to cut mat), T- Square or similar straight edge (to help with straight cuts of mat), tape measure (to measure mat required), marking pen (to identify layers of mat), 3M™ Aluminum Foil Tape 425 (to seal cut edges of mat), rubber roller (to ensure good adhesion of tape), Scotch ® Filament Tape 898 (to temporarily hold mat pieces in place - optional), stainless steel bands 1/2 in. wide x .020 in. min thick (12.7 mm x .5 mm) and band clips or stainless steel tie wire to help secure mat, band tensioners, 3M™ Fire Barrier Sealan t CP 25WB+ (where required). Determine the appropriate number of layers required for your application. Ensure proper covering and protection of joints, seams, overlaps and any area that requires special cutting and fitting. Ensure proper use of banding to mechanically restrain the mat system. Refer to listed system details for sealant, securement requirements, layer requirements and other installation procedures. Maintenance No maintenance is expected to be required when installed in accordance with listed system details. Once installed, if any section of the 3M™ Interam™ Mat I-10/I-10A damaged, the following procedure will ap ply: for damage to the outer metallic covering, install 3M™ Aluminum Foil Tape 42 5 to overlap a min. 2" (50.8 mm) in all directions. For more extensive damage (i ncluding damage to the mat material), contact 3M Fire Protection Products at 1-800-328-1687.
