3M™ Aluminum Tape 433L (with release liner) is suitable for heat protection at high temperatures, e.g., for wrapping thermal insulation. The tape, which features a soft aluminum backing, is coated with a transparent silicone adhesive that withstands temperatures up to 316 °C.

3M™ Aluminum Adhesive Tape 433L (a variant of 433 with release liner) is designed for edging, joining, and sealing in various applications where high temperatures are a concern. This conformable soft aluminum tape is coated with a transparent silicone adhesive that adheres to a variety of difficult-to-bond substrates and forms a strong, reliable bond even at high temperatures. This tape has a temperature resistance range of -54 °C to +316 °C. Furthermore, it meets the flame-retardant requirements of F.A.R. 25.853(a) and is a UL-recognized component (file number QQQW2.MH122798). Recommended applications: • High-temperature radiation reflector • Splicing aluminum foil prior to annealing • Securing the final outer layer of a web from narrow rolls in metal tempering marking • Coating heating elements or cables for heat distribution
