Thermal interface material

Thermal pastes and thermal gels are interface materials used to enhance thermal conductivity between components like CPUs or power electronics and their heat sinks. When used as gap-filling materials, they reduce thermal resistance and help prevent overheating. Also known as thermal greases, thermal pastes are typically thicker, while thermal gels are softer and more conformable.

These materials are formulated from a base compound, often silicone or synthetic polymers, mixed with thermally conductive fillers like metal oxides, silver, or ceramic particles. They are widely used in electronics, automotive systems, LED lighting, and medical devices.
