Thermally Conductive Insulators

As electrical power demands in electronic devices increase, the need for high-performance insulation to reduce heat transfer becomes more important. This is especially true for high-power applications, where heat dissipation can shorten device life or even cause them to fail. Graphene-based materials offer excellent The Power of Thermally Conductive Insulators conductivity and are an ideal choice for applications where thermal management is critical.

However, their cost and availability are challenges for wide use. New materials that offer the advantages of both thermal conductivity and insulating properties are needed. The best of these materials can withstand mechanical stress and provide exceptional strength, making them ideal for use in challenging environments.

A material’s ability to resist thermal transfer depends on its insulating capability, measured as the inverse of its thermal conductivity (k). Low thermal conductivity indicates high insulating capacity. The insulating properties of a material can also be impacted by temperature and pressure.

The insulating properties of a material are also affected by the presence of air gaps in it. Air gaps slow down the flow of heat from the source to the sinker and can significantly reduce a material’s thermal conductivity. A material’s insulating capabilities can also be improved by adding fillers. Typical fillers are metals, metal oxides, and inorganic materials such as silica, beryllia, and cubic boron nitride.

While unfilled polymer adhesives are inherently thermal insulators, by formulating them with metal or other fillers, they can be made to have superior thermal conductivity. CHO-THERM pads are designed for applications where both thermal and dielectric performance is essential. These pads are available with a variety of conductivities and can be die-cut to any shape or size.

In addition to improving thermal and dielectric performance, the pad’s fiberglass reinforcement makes it strong enough for use in a variety of demanding applications. These include EV applications, mother board, power electronics, DDR ll modules, and notebooks.

Choosing the right thermally conductive insulator is critical for many applications in a variety of industries, but it’s particularly important to consider when designing products for harsh or demanding environments. For example, a thermally conductive insulator that can withstand abrasion and a high degree of pressure is essential for aerospace applications. It’s also a great option for medical equipment and industrial automation applications that require an insulator with a high cut-through resistance.

A new class of carbon-ceramic composites has been developed that retains both high electrical conductivity and excellent thermal insulating properties, making them an ideal solution for a number of applications in a variety of industries. This type of material is easy to produce, resistant to mechanical stress, and can withstand extremely high temperatures. This makes it an ideal choice for applications that require both exceptional thermal and electrical properties, including advanced 3D integrated circuit technologies. The materials can help to address the limitations of Moore’s law, which states that the number of transistors on a 2D chip doubles every two years. This limitation is driving the development of 3D IC technology, which incorporates multiple stacked layers of semiconductor materials in one package.
