Industrial-grade high-temperature aluminum foil and glass cloth tape with silicone adhesive, operating range -65°F to 600°F, ideal for aerospace and automotive heat shielding applications
3M™ High Temperature Aluminum Foil/Glass Cloth Tape 363L is a premium linered industrial tape engineered for extreme temperature applications and demanding industrial environments. This specialized tape combines an aluminum foil backing with reinforced glass cloth and pressure-sensitive silicone adhesive to deliver exceptional performance across a wide temperature range from -65°F (-54°C) to 600°F (316°C). The tape features high tensile strength of 135 lb/in and offers superior puncture, fracture, and tear resistance, making it ideal for protecting heat-sensitive cables, instruments, and wire harnesses in aerospace, automotive, and general industrial applications.
The construction of this tape includes a thermally conductive and reflective backing that provides excellent heat shielding properties while resisting flame, moisture, weather, and UV degradation. With its pressure-sensitive silicone adhesive, the tape adheres exceptionally well to difficult surfaces including silicone, and conforms easily to curved or irregular surfaces due to its light and flexible construction. The 7.3 mil thickness provides optimal balance between durability and flexibility, while the linered design makes it suitable for precision die-cutting operations. Each case contains 8 rolls of 4.5 inches width by 108 yards length, offering substantial coverage for industrial operations.
This product meets FAR 25.853(a) specifications and is certified for industrial/occupational use only. It is specifically designed for applications requiring heat reflective wrapping, bundling of wire harnesses, and high-temperature performance in aerospace, automotive, construction, electronics, metalworking, military, and specialty vehicle industries. The combination of advanced materials and proven 3M adhesive technology ensures reliable performance in the most challenging environments.
