Thermal interface silicone material

Thermally conductive silicone, also known as thermally conductive silicone rubber, thermally conductive silicone or thermally conductive silicone, is a high-performance material widely used in electronic components. It is mainly made of organic silicone and is mixed with fillers, thermal conductive materials and other polymer materials. It has good thermal conductivity and electrical insulation properties.

一、Customization of thermal conductive silicone

Thermally conductive silicone can be customized according to specific needs, including adjustment of color, hardness, thermal conductivity, curing time, shape and size and other parameters. The following are the key factors to consider when customizing thermally conductive silicone:

1. Material selection: The basic material of thermal conductive silicone is organic silicone. Different types of thermal conductive fillers, such as spherical alumina powder, silicon carbide powder, zinc oxide powder, etc., can be added as needed to improve its thermal conductivity.
2. Thermal conductivity:Thermal conductivity is an important indicator to measure the thermal conductivity of thermal conductive silicone. Different application scenarios have different requirements for thermal conductivity, so the specific value of thermal conductivity needs to be clarified during customization.

3.Curing time and hardness: Curing time and hardness are also key factors to consider when customizing thermal conductive silicone. Curing time determines the construction efficiency, while hardness affects its use effect.

4.Shape and size: Depending on the specific application, thermal conductive silicone may require different shapes and sizes. When customizing, accurate drawings or size requirements should be provided to ensure that the product meets actual needs.

Performance characteristics of thermal conductive silicone

1. Excellent thermal conductivity:The thermal conductivity of the thermal conductive silicone after curing can reach 1.1~1.5W/(m·k), which provides a high guaranteed heat dissipation coefficient for electronic products and helps to improve the performance and life of the product.
2. Good electrical insulation performance: Thermal conductive silicone has excellent electrical properties, is resistant to aging and hot and cold alternation, is moisture-proof and non-swelling, has a low power decay rate, and increases the safety factor of electronic products during use.
3. High-strength bonding performance: Thermal conductive silicone has good adhesion to electronic components, aluminum, PVC, PBT and other plastics, and has excellent sealing, excellent bonding and thermal conductivity.
4. Easy to operate: Thermal conductive silicone cures quickly, is easy to extrude and does not flow, is easy to operate, can be applied manually or mechanically, and can meet the needs of various working environments and working locations.
