Heat Shielding

Improved longevity, higher heat resistance & precision placement.

How does heat shielding work?

Heat shielding works by reflecting, conducting and radiating heat away from your heat sensitive part. Heat refers to the flow or transfer of thermal energy. Heat flows from a high area to a lower temperature area. There are three forms of thermal energy transfer:

  • icon of conduction from clothing iron

    Conduction occurs when heat passes through a solid, liquid or gas material (molecule transfer). Examples include: the handle on a frying pan/pot, or a clothes iron.

  • icon of convection from radiator

    Convection occurs when heat is transferred via fluid/air movement. Examples of convection include: Radiant baseboard heaters, convection oven, forced air furnace, and liquid cooled engines.

  • icon of radiation from mircorwave

    Radiation occurs when heat is transferred via light or electromagnetic waves, it can be both visible or invisible. Examples of radiation include: sun light, IR light, Incandescent lightbulbs, re, microwave, and solar thermal energy.

Beat the heat with 3M’s portfolio of heat shielding and management materials.

From foil tapes, glass cloth tapes, polyimide tapes, and high temperature double sided tapes to attach your own heat shield. 3M’s network of Converters can assist you with designing a solution for your specic needs.


Mitigating Heat with 3M Converters

Mitigating heat can be as simple and efficient as a peel and stick pressure sensitive tape. Whether it's a foil tape, a glass cloth tape or a double sided tape to attach your own heat shield; they can be fabricated into your desired shape thereby increasing efficiency, aesthetics and enable automation. 3M's network of converters can assist you with design, fabrication and techniques to make you more productive.

Types of Heat Shield Tapes

  • Glass Cloth Tape

    Used in a variety of industries, Glass Cloth Tape is a strong and durable, berglass backed tape designed to perform at high temperatures. It is able to withstand temperatures ranging from -65°F to 450°F (-54°C to 232°C), and intermittent temperatures up to 550°F (288°C) or higher, depending on the type and duration of the heat source.

    Recommended Applications

    • Permanent sealing of high temperature ducts or chambers
    • Applications requiring heat treatment followed by clean removal of the tape with little or no stain
    • Protect surfaces against abrasion
    • High temperature masking
    • Bundling, holding and wire harnessing

  • Foil Tape
    • Is your design melting under the heat from its own components? 3M’s foil tapes can assist you in managing your high temp excursions. 3M’s foil tapes can dissipate heat by reflecting and absorbing emitted heat and conducting it away from the sensitive components. In addition, they’re easy to install as the pressure sensitive adhesive makes it peel, press and move on easy.

      Recommended 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
  • Temporary Heat Shields

    Heat shielding doesn't have to be a permanent solution, there are a lot of temporary heat shields used in manufacturing operations. Perhaps you need to mask parts for a powder coating or other surface treatment operations. Perhaps it's shielding electronic components during the solder reflow process, or other
    processes that may require a bake. 3M has a portfolio of products to help you tackle your heat shielding challenge. On top of the material performance benefits, 3M's network of converters can customize the solution to your problem to make it as easy as peel and press to increase your productivity.
