Abstract: Multi-layer thermally conductive sheets include at least two layers, a core layer and a surface layer. The core layer and the surface layer are simultaneously cured to form a multi-layer sheet where the core layer is tacky, and the surface layer is non-tacky. In some embodiments, the core layer is relatively soft. In other embodiments, the core layer is relatively hard.
