Thermal
conductivity

Encapsulating materials with high thermal conductivity can reliably absorb and dissipate the heat generated by e.g. circuit boards, ICs and motors during operation. Improved control and reduction of hot spots prolong component life and allow even smaller components to be designed.

Effect of thermal conductivity on component temperatures

The thermal conductivities of specially optimised high filler content resins exceed 1.5 W/m·K, while those of unfilled resins are only about 0.2 W/m·K. These optimised materials are available as liquids suitable for encapsulation and as thermal interface material (TIM) pastes.
