(Hot Summer Blog Series)](https://blog.marianinc.com/blog/thermally-conductive-tapes) Posted by [Katie Sullivan](https://blog.marianinc.com/blog/author/katie-sullivan) July 24, 2015 10:03 AM   ![Summer_Blog_Series_copy-1](https://blog.marianinc.com/hs-fs/hubfs/Summer_Blog_Series_copy-1.png?width=631&name=Summer_Blog_Series_copy-1.png) ## Thermally Conductive Tapes Thermally conductive adhesive tape formats are typically transfer tapes or double-coated tapes. (Interested in learning more about tape constructions? [Click here](https://blog.marianinc.com/blog/psa-tape-constructions).)  Adhesive types include thermally conductive acrylic and silicone, which ![png-electronics-page-2](https://blog.marianinc.com/hs-fs/hubfs/png-electronics-page-2.png?width=147&name=png-electronics-page-2.png)are often coated to a support substrate like [polyimide film](https://marianinc.com/wp-content/uploads/2024/07/Material-Spotlight-Polyimide-Films-and-Tapes-WEB-072924.pdf), fiberglass, or aluminum foil. The support substrate adds dimensional stability, which provides ease of handling and allows for clean and precise die cutting.  [Thermally conductive tapes](https://marianinc.com/materials/thermal-management/) create a path to dissipate heat away from a heat-generating component to a heat sink, fan, or other cooling devices. The adhesive creates a better surface contact in the interface joint, reducing thermal resistance and further cooling the device. The high tack of the adhesive provides a strong bond between the two components, often displacing heavy mechanical attachment methods like rivets and screws.    Thermally conductive tapes are typically chosen for their high adhesive strength, reliable long-term performance. They are lightweight and have a thin profile. Most thermally conductive tapes also have a UL94 V-0 flammability rating, which can be a requirement for most electronics applications. These tapes are often used for thermal management in electronics assemblies, LED lighting, and automotive electronics.  Key material suppliers include Polymer Science, 3M, and tesa.    ![787049702pg01im03](https://blog.marianinc.com/hs-fs/hubfs/787049702pg01im03.png?width=152&name=787049702pg01im03.png) #### Custom Components from Marian Marian can [laminate](https://marianinc.com/capabilities/lamination/)thermally conductive tapes to a variety of other materials including foils, films, and foams to create a dynamic part. Marian can also [die-cut](https://marianinc.com/capabilities/die-cutting/) materials into custom shapes and dimensions to fit the exact geometry of the application.  For a sample, quote, or a prototype of thermally conductive adhesive tape, [contact a Marian Engineer.](https://info.marianinc.com/contact-us)    [![Contact Us](https://no-cache.hubspot.com/cta/default/330082/50af1808-237f-48fb-b2c2-c8b634fbef23.png)](https://cta-redirect.hubspot.com/cta/redirect/330082/50af1808-237f-48fb-b2c2-c8b634fbef23)   --- #### Free eBook Download our free eBook below, How to Select the Right Thermal Interface Material.
