Spherical alumina powder for thermal conductive silicone filler

Thermal conductive silicone is a silicone product made by adding thermal conductive fillers and using special processes. Spherical alumina powder has significant advantages as a thermal conductive silicone filler.

The advantages of spherical alumina powder thermal conductive filler are as follows:

1. High thermal conductivity
Spherical alumina has excellent thermal conductivity, which can effectively improve the thermal conductivity of silicone and help to quickly transfer heat.

2. Good liquidity
Spherical particles have good fluidity, making them easy to fill and mix, ensuring even distribution of fillers in silicone gel, and reducing bubbles and voids.

3. Low viscosity
Spherical particles can reduce the viscosity of the mixture, making silicone easier to process and coat.

4. High filling rate
Spherical particles have high packing density and can achieve high filling rate in silicone gel, further improving thermal conductivity.

5. Mechanical properties
Spherical alumina can enhance the mechanical strength of silicone, improve its compressive and tensile properties.

6. Electrical insulation
Aluminum oxide is a good electrical insulation material, suitable for applications such as electronic devices that require electrical insulation.

7. Chemical stability
Alumina has stable chemical properties, high temperature resistance, corrosion resistance, and can maintain performance in harsh environments.

8. Controllable particle size
Spherical alumina can be selected in various particle sizes, ranging from 2um to 90um, to meet different application requirements.

As a whole, spherical alumina powder is an ideal filler for thermal conductive silicone due to its advantages in thermal conductivity, fluidity, filling rate, mechanical properties, electrical insulation, and chemical stability.
