Silicone-free thermal interface materials

Five Key Points for Optimal Use:

In many applications, thermal pads and thermal gels are commonly used due to their physical properties, often containing silicone. However, silicone can bleed or outgas in small amounts, making it unsuitable for use in areas such as the optical industry, vacuum environments, or near paint shops. For these specific applications, Infratron offers high-quality silicone-free thermal interface materials. To use these materials effectively, the following five key points should be observed:

1. Material Selection
Ensure that the selected silicone-free thermal interface material meets at least the required thermal conductivity. Compared to silicone-based materials, silicone-free options are often less soft and have lower thermal conductivity. Therefore, carefully choose the appropriate material for your application to ensure efficient heat transfer.

2. Material Thickness
The thickness of thermal pads is a critical factor in their efficiency. Thinner pads provide higher thermal conductivity, while thicker pads are better at compensating for tolerances and surface irregularities. Make sure to choose the optimal thickness to meet the specific requirements of your application.

3. Operating Temperature
Check the maximum operating temperature of the silicone-free thermal material. These materials may have varying temperature limits that are critical for your specific application. Ensure that the selected material functions reliably under the expected temperatures.

4. Aging Resistance
Silicone-free thermal interface materials are often more durable than silicone-based alternatives. However, pay attention to the aging resistance of the material, especially if it will be used in environments with high temperatures or extreme conditions. High aging resistance ensures that the material remains reliable over extended periods.

5. Application Process
The application of silicone-free thermal materials requires special care. A clean and even application of thermal pads and gels is essential for efficient heat transfer. Avoid air pockets, as these can impair the effectiveness of heat conduction.
