3M high temperature aluminum foil/glass cloth tape 363 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. Heat reflective wrap over insulation cables, instruments or other high temperature sensitive materials. - 3M high temperature aluminum foil/glass cloth tape 363 consists of an aluminum foil, glass cloth backing combined with a pressure sensitive silicone adhesive. Ideal for use as a protective wrap for heat sensitive cables and other instruments exposed to movement and vibration. It is a chemical resistant, thermally conductive tape that performs consistently at temperatures ranging from -65 to 600 °F.
