Best Materials for Dissipating Heat in Electronics

Materials technology has rapidly advanced. This has led to breakthroughs in electronic components. They have improved in high frequency, high speed, and integrated circuits. Electronic components have gotten smaller. But, total power and heat flow have increased a lot. Heat is flowing more quickly. This requires good cooling in electronics. It’s needed to keep them working well and reliable.

In smartphones, for example, the rising main frequency of smartphone chips creates much heat. This heat harms user experience and can damage hardware. Since 2019, heat dissipation in electronics has become a key market focus. For example, Xiaomi’s Black Shark smartphone has a multi-stage, direct-touch cooling system. This system uses copper sheets with a small amount of built-in liquid to dissipate heat, ensuring optimal performance and hardware protection efficiently.

General Application of Heat Dissipation Materials for Electronic Products

Heat dissipation is crucial for electronic components. It controls device temperature and improves performance. This process involves various material properties to ensure effective thermal management.

The surface of electronic materials and heat sinks often have fine, uneven gaps. If these parts are installed right next to each other, their actual contact area is only about 10% of the heat sink’s base area. The rest is air gaps. Air has a very low thermal conductivity at only 0.024W/(m. K). So, these air gaps create high thermal resistance. This resistance is between the electronic components and the heat sink. It seriously hinders heat conduction and reduces the heat sink’s performance.

To fix this issue, we use thermal conductive materials to fill these gaps. This greatly increases the contact area between parts that make heat and parts that remove heat. This results in improved heat dissipation. We are experts in thermal management. Trumonytechs offers a range of thermal conductive materials. These include silicone film, silicone grease, potting adhesive, and gel.

These materials greatly improve heat dissipation in electronics. They ensure that electronic parts stay at optimal temperatures and perform well.

Comparison of Several Electronic Heat Dissipation Materials

This section is about the introduction of heat-dissipation materials used in electronics. They include thermal conductive silicone film, thermal conductive silicone grease, thermal conductive gel, and thermal conductive potting adhesive.

Thermal Conductive Silicone FilmThis film is made from silicone, with added metal oxides. It is made through a special process to create a thermally conductive medium. It is usually a soft, tearable sheet that can be cut into different sizes as needed. This material is great for filling gaps. It also manages heat well in many electronic devices.

Thermal Conductive Silicone Grease: It is a thick, viscous material. It is made mostly from silicone. Heat-resistant and thermally conductive materials are added. It is commonly used for thermal conductivity contact in CPU and GPU components, ensuring efficient heat transfer and dissipation.

Thermal Conductive GelThermal conductive gel is a semi-solid material that resembles a paste. It is well-formed, non-flowing, and has low volatility, similar to Play-Doh. It has a higher viscosity than thermal silicone grease. It usually does not need to be applied directly to the parts that need to dissipate heat. Instead, it can be filled directly into gaps, making it suitable for various electronic applications.

Thermal Conductive Potting AdhesiveIt is made from epoxy resin filled with heat-conductive powder. It also has hardeners and accelerators. It offers excellent thermal conductivity, high-temperature stability, and mechanical strength. This adhesive is used for thermal conductivity, potting, sealing, and fixing electronic components, providing protection and effective heat dissipation.

In summary, these materials can transfer and dissipate heat. They have different physical properties and uses. Picking the right thermal material depends on the application’s needs and equipment type.

How to Choose the Right Electronic Thermal Products?

Choosing the right electronic thermal products is crucial. They are key for effective heat dissipation and the performance of electronic devices. Here’s a guide to selecting the appropriate thermal conductive materials based on specific applications and needs:

Thermal Conductive Silicone Film: This silicone film is good for filling gaps between uneven surfaces or connectors. It is used in small electronic devices like smartphones, tablets, and laptops. It ensures stability and resists vibration and shock while maintaining thermal conductivity. This film is also good for larger electronic devices. These include servers, industrial control machines, and LED lights. It is good for them due to its high heat tolerance and non-flowing properties.

Thermal Conductive Silicone Grease: The grease conducts heat well. It is stable and works at very high temperatures. It does not flow or evaporate easily. This makes it good for filling gaps in big electronic devices like servers, control machines, and LED lights.

Thermal Conductive Gel: Thermal conductive gel is perfect for fixing thermal components and filling uneven voids on surfaces. It is stable at high temperatures due to its high thickness and thermal conductivity. It is suitable for cooling in power supplies and car electronics. The gel provides effective heat management while ensuring that components remain securely in place.

Thermal Conductive Potting Adhesive: People commonly use thermal conductive potting adhesive for potting electronic components. It enhances heat dissipation and provides mechanical protection. It offers high thermal conductivity, heat resistance, sealing, and mechanical strength. This adhesive protects electronic components from the environment. It is good for use in power supplies, batteries, transformers, and inductors.


Good heat dissipation is crucial for electronics. It maintains their performance and longevity. Select the right materials for thermal conduction, such as thermal silicone film, grease, gel, and potting adhesive. These can greatly improve how your devices manage heat. Each material has unique properties and uses. It’s vital to choose based on needs and equipment types.
