Silicone-free thermal pads lead a new trend in heat dissipation

Thermal conductive silicone sheets are made of silicone oil base material and other thermally conductive, heat-resistant, and insulating materials mixed in proportion, and are used to fill the tiny gaps between interfaces. However, in an environment exposed to heat and pressure for a long time, the small molecule siloxane in the silica gel sheet may slowly precipitate. Therefore, the precipitation of silicone oil when using thermally conductive silicone sheets is an unavoidable phenomenon.

Taking this into account, researchers have developed a new type of thermal interface material-silicon-free thermal pad. This innovative material does not use silicone oil as a raw material, effectively avoiding the problem of silicone oil precipitation and thus not causing contamination to circuit boards or electronic components. At the same time, silicone-free thermal pads retain all the advantages of traditional thermally conductive silicone sheets, such as excellent thermal conductivity and filling performance. Although silicone-free thermal conductive sheets are not completely oil-free, their composition does not affect the performance of the device, so it is known as an environmentally friendly thermal interface material.

Today, when high-precision instruments and high-tech equipment are widely used, the heat generated by machines and equipment when powered on needs to be effectively managed. Thermal interface materials, such as silicon-free thermal pads, can effectively reduce the contact thermal resistance between the device heat source and the radiator, fill the gaps between the interfaces and eliminate air, thereby accelerating heat transfer and improving heat dissipation effect.

All in all, silicon-free thermal pads, as a new type of environmentally friendly thermal interface material, show great potential in the heat dissipation management of modern electronic equipment. They not only improve the heat dissipation efficiency, but also provide a more environmentally friendly guarantee for the stable operation of the equipment.
