The Difference between Thermal Conductive Silicone And Thermal Conductive Grease

When it comes to the heat dissipation of electronic devices, thermal conductive materials are an indispensable choice. Thermal conductive silicone and thermal conductive grease are two common heat dissipation materials, but they are very different in use, performance and application scenarios.

What is thermal conductive silicone?

Thermal conductive silicone is a solid thermal conductive material that usually appears in the form of sheets or gaskets. It consists of silicone and thermal conductive fillers, with good flexibility and insulation properties.

Advantages of thermal conductive silicone:

1. Easy to install: It can be directly attached to the surface that needs heat dissipation without flowing or overflowing.

2. High durability: Suitable for long-term use, not easy to age or harden.

3. Electrical insulation: While dissipating heat, it can also protect electronic components from short circuits.

4. Diversification: The thickness and shape can be customized according to needs.

Common application scenarios:

· Computer processors and graphics cards

· LED lamps

· Battery packs and power modules

What is thermal conductive grease?

Thermal grease is a paste-like thermal conductive material, which is a mixture of silicone oil and thermal conductive filler. Its main function is to fill extremely small uneven surfaces, thereby reducing air gaps and improving thermal conductivity.

Advantages of thermal grease:

1. High thermal conductivity: It has extremely high thermal conductivity and is suitable for high-performance electronic devices.

2. Strong filling ability: It can perfectly cover tiny surface unevenness.

3. Flexible use: Suitable for devices of various sizes and shapes.

Common application scenarios:

· Between computer CPU and radiator

· GPU chip

· High-frequency communication equipment

Thermal conductive silicone and thermal conductive grease each have their own advantages and disadvantages. When choosing, you need to decide according to the specific needs of the device.
