Why is there poor heat conduction when using thermally conductive silicone sheets on laser machines?

When we choose the type of thermally conductive silicone sheet, an important parameter is the thermal conductivity. Although this is important, in fact, the hardness, thickness and blocking voltage of the thermally conductive silicone sheet will also largely affect the thermal conductivity of the product. Choose the thermal conductivity of the thermally conductive silicone sheet. It is necessary to consider the shape, specifications, and heat resistance of the product before comprehensively selecting a suitable thermally conductive silicone sheet. It does not mean that the higher the thermal conductivity, the more suitable it is, and the better the conduction.The thermal conductive silicone sheet product coefficient of a certain company on the market is 3.0 and the thickness is 0.8. When applied to a laser machine, the thermal conductive silicone sheet is too soft and does not have a good effect in conducting heat. This shows that the selected thickness is slightly different.Because the thermal conductivity
