Why do European customers choose non-silicon thermal pads for LEDs?

Taking non-silicon thermally conductive pads as an example, when a European customer of the author chooses thermally conductive materials for the development of LED lamp sets, he consulted our company on thermal conduction solutions and requested green, environmentally friendly, pollution-free, and thermally conductive materials with stable thermal conductivity. SHEEN can provide 1-8W / m-K thermally conductive silicone sheets and non-silicon thermally conductive gaskets. In terms of thermal conductivity, thermally conductive silicone sheets and non-silicon thermally conductive gaskets are comparable. However, non-silicon thermal pads have the irreplaceable advantages of traditional thermal silica gel sheets:

Non-silicon thermal pads do not contain silicone oil or volatile silicone. When used at high temperature, traditional silicone rubber sheets will precipitate silicone oil and attach to the product, which affects the performance and stability of the product, especially for precision optical equipment. The impact on the product is more obvious. For the LED industry, the volatilization of silicone oil will directly lead to light decay, while the non-silicon thermal pad does not have this problem. There is no siloxane volatility and no light decay to ensure the stability of the product. Sex.
       The non-silicon thermally conductive pads has good flexibility and high compressibility, which can make the heat source and the heat sink contact more closely, squeeze out the air, reduce the thermal resistance, and improve the thermal conductivity. Compared with the traditional thermally conductive silica gel sheet, the density of the non-silicon thermally conductive pads To be lower, to reduce the overall weight of the product, more in line with the development trend of thin and light products.
