High Thermal Conductivity Silicone Thermal Gap Pad
SENMA Thermal Gap Pads are engineered to efficiently transfer heat from electronic components to heat sinks or metal enclosures, helping improve thermal management and extend the service life of electronic devices.
Made from premium silicone elastomer filled with highly thermally conductive ceramic particles, our thermal interface pads offer excellent thermal conductivity, electrical insulation, and outstanding conformability. The soft material easily fills uneven gaps between components, reducing thermal resistance while minimizing mechanical stress on sensitive devices.
Available in a wide range of thermal conductivity levels, thicknesses, and hardness options, SENMA thermal gap pads are widely used in consumer electronics, telecommunications, automotive electronics, LED lighting, power supplies, industrial equipment, and new energy battery systems.
