How to choose a high-performance thermally conductive silicone sheet?

In modern electronic devices, LED lighting, automotive industry and other fields, efficient thermal management is essential. Thermally conductive silicone sheet has become an ideal choice for solving thermal management problems due to its excellent thermal conductivity and reliability. However, there are many types of thermal conductive products on the market. How to choose high-performance products to meet specific needs?

1. Understand thermal conductivity

Thermal conductivity is a key indicator to measure the ability of thermally conductive materials to conduct heat. When selecting products, you should pay attention to the specific value of thermal conductivity, which is usually expressed in watts per meter per Kelvin (W/m·K).

Recommendation: Choose a thermally conductive silicone sheet with a thermal conductivity range of 1.5 - 3.0 W/m·K to ensure that it has good thermal conductivity in most application scenarios.

2. Check the operating temperature range

The operating temperature range of thermally conductive silicone sheet determines its applicability under different environmental conditions.

Recommendation: Make sure that the selected silicone sheet has good performance stability within the temperature range of your application environment.

3. Consider mechanical properties

The mechanical properties of thermally conductive silicone sheet, such as tensile strength and shear strength, are also important factors in evaluating its quality. These properties affect the durability and service life of silicone sheets, especially in environments where they are subjected to physical pressure or deformation.

Recommendation: Choose products with a tensile strength of 2.0 - 3.5 MPa and a shear strength of 1.5 - 2.5 MPa to ensure its stability and reliability in practical applications.

4. Pay attention to conductivity

Although thermally conductive silicone sheet is mainly used for thermal management, its conductivity cannot be ignored. Low conductivity (usually in the order of 10^-14 S/cm) means that the silicone sheet performs well in electrical insulation and is suitable for application scenarios that need to prevent electrical interference.

Recommendation: Make sure the silicone sheet has good electrical insulation properties to avoid potential electrical problems.

5. Look for suppliers' OEM and ODM services

If you have special design needs or mass production requirements, choosing a supplier that can provide OEM (original equipment manufacturing) and ODM (original design manufacturing) services will greatly simplify your procurement process. Leading manufacturers such as JiaheWell provide customized services and can provide thermally conductive silicone sheet solutions tailored to your needs.
