1、 Overview of PEEK Materials
PEEK is a high-performance special engineering plastic with excellent mechanical properties, chemical stability, and high temperature resistance. However, traditional PEEK materials have certain limitations in terms of thermal conductivity and insulation performance. In order to meet the growing demand for high-performance applications, researchers have successfully developed PEEK materials with high thermal conductivity and insulation properties through continuous research and innovation.
2、 Advantages and characteristics of high thermal conductivity
The PEEK high thermal conductivity material with a thermal conductivity of 35W/m.K exhibits excellent heat transfer capability.
This high thermal conductivity enables PEEK to quickly transfer heat from the heat source, effectively preventing local overheating. This feature is crucial in electronic devices. For example, in the packaging of integrated circuit chips, high thermal conductivity PEEK material can help the chip dissipate heat quickly, ensure its stable operation, and improve the reliability and service life of the equipment.
Compared with traditional thermal conductive materials, the high thermal conductivity of PEEK can be achieved without sacrificing other excellent properties. It not only has excellent thermal conductivity, but also maintains the high strength, high rigidity, and chemical corrosion resistance of PEEK itself.
Taking electronic device heat sinks as an example, traditional metal heat sinks, although having good thermal conductivity, have problems such as heavy weight and susceptibility to corrosion. The heat sink made of PEEK polyether ketone high thermal conductivity material not only efficiently dissipates heat, but also has the advantages of lightweight and corrosion resistance, providing a guarantee for the lightweight and long-term stable operation of equipment.
3、 The Importance of High Insulation Performance
High insulation performance is one of the key characteristics of PEEK polyether ketone in the field of electronic and electrical applications. It has a very high resistance value, which can effectively prevent the conduction of current and ensure the safe operation of electrical equipment in high voltage and complex electromagnetic environments.
In high-voltage transmission lines, the performance of insulation materials is directly related to the stability and safety of power transmission. The high insulation performance of PEEK polyether ketone can reduce the occurrence of leakage and discharge phenomena, lower power losses, and improve transmission efficiency.
In the interior of electronic devices, high insulation PEEK material can be used to manufacture various insulation components, such as circuit board substrates, insulation gaskets, etc., to prevent short circuits and interference between circuits and ensure the normal operation of the equipment.
4、 Preparation process of PEEK high thermal conductivity and high insulation material
The key to achieving high thermal conductivity and insulation performance of PEEK polyether ketone lies in its unique preparation process.
A common method is to improve thermal conductivity by filling thermal conductive fillers. Common thermal conductive fillers include boron nitride, aluminum oxide, carbon fiber, etc. These fillers form effective thermal conductivity pathways in the PEEK matrix, significantly improving the material's thermal conductivity.
At the same time, in order to ensure high insulation performance, it is necessary to strictly control the content and distribution of fillers during the preparation process, to avoid the formation of conductive pathways by fillers, which may affect insulation performance.
In addition, optimizing processing parameters such as temperature, pressure, and molding time is crucial for obtaining high-performance PEEK materials.
5、 Wide expansion of application fields
Due to its unique performance combination, PEEK high thermal conductivity and high insulation material has been widely used in many fields.
In the field of electronics and electrical engineering, it is used to manufacture high-performance electronic packaging materials, printed circuit boards, connectors, etc. For example, in mobile devices such as smartphones and tablets, PEEK with high thermal conductivity and insulation can effectively solve the problems of chip heat dissipation and circuit insulation, improving the performance and stability of the equipment.
In the aerospace field, PEEK's lightweight, high thermal conductivity, and high insulation properties make it an ideal material for aircraft and satellite electronic equipment. It can be used to manufacture components for satellite communication systems, control systems for aircraft engines, etc., ensuring the normal operation of equipment in extreme environments.
In the field of new energy vehicles, PEEK material can be used for battery management systems of electric vehicles, insulation components of drive motors, etc. High thermal conductivity helps to dissipate heat from batteries, improving their safety and lifespan; High insulation performance ensures the stable operation of the electrical system.
