With thermal conductivity of 8.0 W/m·K, low thermal impedance, and excellent extrusion properties, it helps create close contact between surfaces, reduce interfacial thermal resistance, and improve heat dissipation efficiency. As part of SHEEN’s SE Series 1K Thermal Gel family, SE80 combines softness, compressibility, stable dispensing performance, and reliable electrical insulation. It is especially suitable for projects that require stronger heat transfer performance, low assembly stress, and flexible gap filling in complex electronic structures. ### Key Benefits - Thermal conductivity: 8.0 W/m·K - Low thermal impedance for efficient heat transfer - Good flexibility and high filling rate for large gap tolerance designs - Excellent extrusion properties and stable dispensing performance - Suitable for manual application or automated dispensing - Reliable electrical insulation performance - Excellent flame resistance, UL94 V-0 - Available in 30cc / 300cc packaging - Compliant with RoHS, Halogen-Free, and REACH requirements Categories: [Thermal interface materials](https://www.sheenmaterials.com/tim/) , [Paste/Liquid](https://www.sheenmaterials.com/paste-liquid/) , [Single-Component Thermal Conductive Gel](https://www.sheenmaterials.com/single-component-thermal-conductive-gel/) Share your love[https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.sheenmaterials.com%2Fse80-thermal-gel-8-w-mk%2F](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.sheenmaterials.com%2Fse80-thermal-gel-8-w-mk%2F) [https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fse80-thermal-gel-8-w-mk%2F&text=SE80%20Thermal%20Gel%208.0%20W%2FmK](https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fse80-thermal-gel-8-w-mk%2F&text=SE80%20Thermal%20Gel%208.0%20W%2FmK) [#](#) [https://www.linkedin.com/shareArticle?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fse80-thermal-gel-8-w-mk%2F&title=SE80%20Thermal%20Gel%208.0%20W%2FmK](https://www.linkedin.com/shareArticle?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fse80-thermal-gel-8-w-mk%2F&title=SE80%20Thermal%20Gel%208.0%20W%2FmK) - [描述](#tab-description) ## Technical Information Review the key specifications, recommended applications, installation notes, and downloadable files for SE80.
