Gobal Leader in Thermal Interface Materials

Thermal Silicone Caps - Thermal Conductive

We specialize in developing world-class thermal management materials for use in electric vehicles, motors, LED lighting and other power electronics, such as DC/DC converters and solar micro inverters.

Thermal silicone insulator caps are made of silicone filled with highly thermally conductive ceramics. Depending on material gauge, the all-round electric insulation of the components ensures maximum protection against electrical breakdown while reducing total thermal resistance to the cooling element, heat sink or chassis. SinoGuide thermo-silicone caps are available in dimensions compatible with standard casings TO-220, TO-3P and TO-247.
