INTRODUCTION TO THERMALLY CONDUCTIVE POLYMER
With the rapid progress of science and technology and the information industry, electronic products tend to be light weight and compact, and their installation space is becoming very limited, so that the high efficiency and ease of operation of conduction heat dissipation are also becoming more and more important and urgent. For this demand, the use of thermally conductive polymer materials have many advantages, such as: good electrical insulation, strong corrosion resistance, excellent mechanical and fatigue resistance, lighter weight and easy to process and so on.
The principle of thermally conductive material is to add thermal conductivity fillers to the polymer to form thermal conductivity polymer composites. Its thermal conductivity is determined by the thermal conductivity filler and its distribution in the polymer matrix. When the fillers interact with each other, a web-like or chain-like heat-conducting networks are formed. When the direction of heat flow is consistent with the direction of the heat-conducting links inside material, the thermal resistance is the lowest and the performance is the best, and vice versa. After years of testing and practice, GoodBon has accumulated many experiences in thermal conductivity theory, application and production. The fillers' type, distribution in the material, size, characteristic, the way of mixing, amount used will all affect the thermal conductivity of polymer composites. In the engineering design and practical application of thermally conductive materials, the main purpose is to improve the heat conduction efficiency, solve the matching between irregular surfaces and build a thin interface layer with low thermal impedance. This layer can effectively eliminate the air gap and improve the heat conduction. Common types of thermally conductive materials are: pad, thermally conductive gel, potting compound, adhesives, phase change material, grease, graphite film, and thermally conductive insulating materials, etc. The specific selection guide and parameters are described in detail in the following pages.
