HS419 Thermalsil Thermally Conductive Silicone Rubber Insulator
The newest Thermalsil™ III formula has improved thermal conductivity, providing excellent thermal resistance. It is used as an electrically-isolating interface material. Thermalsil™ III eliminates the need for grease and conforms to mounting surfaces under clamping pressure for optimum conductivity. The 53-77-9 is mostly used for TO-220 packaging.
