Details
  • Linered version of 3M™ High Temperature Aluminum Foil Tape 433
  • Can withstand limited exposure up to 600°F/316°C 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)

For heat shielding applications such as wrapping over and thermal insulation, use 3M™ High Temperature Aluminum Foil Tape 433L. 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.

3M™ High Temperature Aluminum Foil Tape 433 is designed to excel in a variety of seaming, splicing and sealing applications where high temperatures are a concern. This dead soft, aluminum-backed tape is coated with a pressure-sensitive silicone adhesive that bonds to a variety of difficult substrates while maintaining a strong and reliable bond, even at high temperatures. This tape boasts an excellent performance range from -65 °F to 600 °F (-54 °C to 316 °C) and meets flame resistance requirements of F.A.R. 25.853(a) and is a UL Recognized component.

Suggested Applications

  • High temperature heat shielding applications
  • Splice jumbo rolls of aluminum foil
  • Hold last lap of narrow width rolls during metal annealing process
  • Cover heating elements or wires to distribute heat
