Premium high-temperature aluminum foil glass cloth tape with silicone adhesive for extreme industrial applications. Operates from -65°F to 600°F with superior tensile strength, flame resistance, and thermal conductivity.
3M™ High Temperature Aluminum Foil/Glass Cloth Tape 363 is a versatile, industrial-grade tape engineered for extreme temperature applications and demanding environments. This premium tape features high tensile strength combined with outstanding puncture and tear-resistance, making it ideal for aerospace, automotive, and general industrial applications. The heat-reflective aluminum backing is reinforced with robust glass cloth to create a strong, conformable backing that adheres well to irregular and uneven surfaces.
Coated with a pressure-sensitive silicone adhesive, this tape performs consistently across an exceptional temperature range from -65°F to 600°F (-54°C to 316°C). It resists flame, moisture, weather, and UV degradation while providing exceptional thermal conductivity. The lightweight, flexible construction helps it conform to curved and irregular surfaces, making it perfect for bundling wire harnesses, heat reflective wrapping over insulation, cables, instruments, and high-temperature sensitive materials. The tape meets F.A.R. 25.853(a) specifications and is suitable for applications exposed to movement and vibration.
With its combination of superior strength, heat resistance, and reflectivity, 3M™ High Temperature Aluminum Foil/Glass Cloth Tape 363 delivers reliable performance in the most challenging industrial environments. Each case contains 48 rolls of 36-yard tape with a 3/4-inch width, providing ample material for large-scale industrial operations. This product is intended for industrial and occupational use only.
