Aluminum foil tape is a special type of tape made with aluminum foil as the base material and coated with pressure-sensitive adhesive. It has excellent high-temperature resistance, moisture resistance, heat insulation, and electromagnetic shielding properties. Common widths are 50mm-100mm, thicknesses are 0.05mm-0.1mm, and the temperature range is typically -20℃ to 150℃. Aluminum foil tape is widely used in pipe insulation, electronic equipment shielding, and HVAC system sealing. When purchasing, pay attention to the initial tack and holding power of the adhesive.
