WARNING: Raw materials are not sold separately, please contact the sales department for any special requirements.


    ISOSAM-300/5 provides heat barrier protection by utilizing a moderate-temperature composite material consisting of aluminum foil bonded to fiberglass with a special HT-adhesive. On the reverse side a 4.5mm 100% Preox fiber felt layer is laminated to the material, which assists with heat insulation and abrasion resistance.

    Heat shielding materials are commonly used throughout the automotive industry in various applications. For instance, to protect critical engine wiring, prevent vapor lock, and improve vehicle efficiency by blocking radiant heat caused by temperatures under the hood.

    ISOSAM-300/5 has an operational temperature range of -40°F to 392°F (-40°C to 200°C) with a maximum of 482°F (250°C) for a short duration.
