Every chip that runs faster generates more heat, and every gigawatt of AI computing capacity adds pressure on the materials that move that heat away. That is why the thermal interface materials market has moved from a quiet supporting role to a strategic priority for semiconductor makers, data center operators, and automakers alike. According to IG Transformation Partners, the thermal interface materials market size was valued at USD 4.4 billion in 2025 and is projected to reach USD 11.9 billion
