Thermalsil III Thermally Conductive Silicone Rubber Insulators The newest Thermalsil III formula has improved thermal conductivity, providing excellent thermal resistance. It is used as an electrically-isolating interface material composed of silicone elastomer binder with a thermally conductive filler. It is reinforced with glass cloth to resist tearing and cut-through due to burrs on transistors or heat sinks. Thermalsil III eliminates the need for grease application and conforms to mounting surfaces under clamping pressure for optimum heat conduction. Thermalsil III is .152mm (.006 ) thick and grey green in color. A finely woven glass cloth provides the thinnest possible matrix for enhanced thermal resistance. To order Thermalsil III with adhesive coated backing, add suffixA to the part number. For example, 53-03-2AC. Thermalsil III is available in any configuration with adhesive backing. Order by addingA after the part number. For example: 53-03-2AC.
