For heat shielding applications such as wrapping over and along thermal insulation, use 3M High Temperature Aluminum Foil Tape 433. This dead soft aluminum foil tape is coated with a clear silicone pressure sensitive adhesive that bonds well to a variety of surfaces and excels in high temperature applications, where other adhesive tapes may fail.

  • Can withstand limited exposure up to 600ºF/316ºC for heat shielding applications
  • Thermally conductive tape helps dissipate heat to protect temperature sensitive materials
  • Can be used to improve heating and cooling efficiency
  • Dead soft aluminum foil backing conforms to curved and uneven surfaces
  • Flame resistant – meets requirements of F.A.R. 25.853(a)
  • UL Recognized component (file QQQW2.MH122798)
