China Suppliers Thermal Pads - High-Quality Factory Heat Transfer Solutions for Optimal Cooling Performance

Silicone thermal pad is a soft thermal conductive medium made of silicone rubber as the base and filled with high thermal conductivity insulating materials. It is specially used for heat transfer between heat-generating components and heat sinks in electronic equipment. Its core function is to fill the microscopic gaps on the contact surface, reduce the interface thermal resistance, and thus efficiently conduct heat, while providing electrical insulation and mechanical buffer protection.

1. Thermal conductivity: The higher the thermal conductivity, the lower the thermal resistance and the better the thermal conductivity.

2. Thickness: Thinner pads have low thermal resistance and good heat transfer effect.

3. Hardness and softness: Gaskets with low hardness fit surfaces better, reducing contact thermal resistance.

4. Working temperature range: Ensure the range is suitable for the equipment's environment.

Other factors: Pressure resistance, toughness, silicone oil content, and fire rating.

Thermal conductive pads are widely used in many fields such as electronic products, medical applications, automotive industry, aerospace, home appliances, power supply industry, LED industry and PC equipment.

1. Type and characteristics of polymer matrix materials.

2. Type, shape and content of fillers (whisker > fiber > flake > granular).

3. Humidity: Higher humidity can negatively affect thermal conductivity.

4. Thickness: Thinner materials provide higher conductivity efficiency.

5. Built-in substrate: Reinforcements used for tensile strength.

The method of using silicone thermal pads mainly includes steps such as cleaning the surface, cutting the size, pasting the gasket, removing bubbles and fixing the installation. Proper pressure and surface contact are essential for performance.
