With thermal conductivity of 4.0 W/m·K, low interfacial thermal resistance, and excellent thixotropy, it helps create close contact between surfaces, reduces thermal resistance, and improves heat dissipation efficiency. As part of SHEEN’s SE Series 1K Thermal Gel family, SE40 combines softness, compressibility, stable dispensing performance, and reliable electrical insulation. It can be applied manually or with dispensing equipment, making it suitable for projects requiring controlled material placement, low assembly stress, and flexible gap filling in complex electronic structures. ### Principais benefícios - Condutividade térmica: 4,0 ± 0,4 W/m-K - Lower thermal resistance for more efficient heat transfer - Boa flexibilidade e elevada taxa de enchimento para projectos com grande tolerância de folga - Excelente tixotropia e desempenho de distribuição estável - Adequado para aplicação manual ou distribuição automática - Desempenho fiável do isolamento elétrico - Excelente retardamento de chama, UL94 V-0 - Disponível em seringas de 30CC / 300CC e embalagens de bidão - Em conformidade com os requisitos RoHS, de halogéneos e REACH Categorias: [Materiais de interface térmica](https://www.sheenmaterials.com/pt/tim/) , [Pasta/Líquido](https://www.sheenmaterials.com/pt/paste-liquid/) , [Gel condutor térmico monocomponente](https://www.sheenmaterials.com/pt/single-component-thermal-conductive-gel/) Partilhe o seu amor[https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.sheenmaterials.com%2Fpt%2Fse40-thermal-gel-4-w-mk%2F](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.sheenmaterials.com%2Fpt%2Fse40-thermal-gel-4-w-mk%2F) [https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fpt%2Fse40-thermal-gel-4-w-mk%2F&text=SE40%20Thermal%20Gel%204.0%20W%2FmK](https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fpt%2Fse40-thermal-gel-4-w-mk%2F&text=SE40%20Thermal%20Gel%204.0%20W%2FmK) [#](#) [https://www.linkedin.com/shareArticle?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fpt%2Fse40-thermal-gel-4-w-mk%2F&title=SE40%20Thermal%20Gel%204.0%20W%2FmK](https://www.linkedin.com/shareArticle?url=https%3A%2F%2Fwww.sheenmaterials.com%2Fpt%2Fse40-thermal-gel-4-w-mk%2F&title=SE40%20Thermal%20Gel%204.0%20W%2FmK) - [Descrição](#tab-description) ## Informações técnicas Review the key specifications, recommended applications, installation notes, and downloadable files for SE40.
