    Product Description

    3M 363 high temperature aluminum foil glass cloth tape can be used as a high temperature, heat reflective, protective wrap for certain cables and other components in aerospace and industrial applications.

    3M 363 high temperature aluminum foil/glass cloth tape is a strong and flexible tape with high tensile strength, puncture and tear resistance. With a pressure sensitive silicone adhesive, it adheres well to silicone surfaces and over irregular or uneven substrates. This tape is light and heat reflective, plus it resists flame, moisture, weather and UV degradation. It is a chemical resistant, thermally conductive tape that performs consistently at temperatures ranging from -65°F/-54°C to 600°F/316°C

    1. Can easily be die-cut into special sizes or shapes.
    2. Light, flexible construction – easily applied to a variety of irregular shapes.
    3. Performs continuously from -65°F (-54°C) to 600°F (316°C).
    4. Best results obtained when applied to a clean dry surface above 32°F (0°C), but can be applied at lower temperatures.
    5. High tensile strength, glass cloth reinforced foil tape offers puncture, fracture and tear resistance.
    6. Thermally conductive and reflective backing assists with heat shielding.
    7. Pressure sensitive silicone adhesive adheres to difficult surfaces, including silicone.
