3M Adhesive Tape 433, Linered

The 3M™ Aluminum Tape 433 is a high-temperature-resistant, thermally conductive adhesive tape with a soft aluminum backing and a transparent silicone adhesive that withstands temperatures from -54 °C to +316 °C. It was specifically developed for applications where extreme heat, flames, moisture, or chemicals pose a challenge.

This flexible aluminum adhesive tape conforms effortlessly to curved and uneven surfaces and offers excellent flame, moisture, weather, UV, and chemical resistance. It is flame-retardant and meets the requirements of F.A.R. 25.853(a) as well as UL component recognition (File No. QQQW2.MH122798).

Thanks to its thermal conductivity, the tape supports efficient heat dissipation, protects temperature-sensitive materials, and can help improve heating and cooling efficiency. This makes it ideal for use in high-temperature environments, such as a radiation reflector, protective covering, or bonding material in industrial processes.

3M™ Aluminum Tape 433 is the first choice for technical applications where heat resistance, reliability, and protection are critical—from aerospace to electronics manufacturing.
