Polysilazane has significant advantages in insulation materials, as follows:
Excellent electrical insulation performance
High resistance characteristics: The material formed by curing polysilazane has a high electrical resistivity, which can effectively block the conduction of current, making it difficult for electrons to move inside and form current. This lays a solid foundation for its use as an insulating material. Whether between tiny electronic components or in critical insulation areas of large power equipment, this high resistance characteristic can reliably prevent electrical faults such as short circuits and ensure the normal operation of circuits and equipment.
Low dielectric constant and low dielectric loss: It has a low dielectric constant, which means that under the action of an electric field, the ability of the material to store electrical energy inside is relatively weak, and polarization phenomena are not easily generated, thereby reducing the distortion and energy loss of the electric field in the material. At the same time, low dielectric loss also ensures that materials will not consume too much electrical energy and generate heat due to repeated polarization and depolarization processes in alternating current environments. This is crucial for ensuring the efficient and stable operation of electronic devices and maintaining long-term stability of insulation performance.
Good thermal stability
Resistant to high temperature environment: In the field of electronics and electrical engineering, many devices and components will face high temperature environments during operation. For example, electronic chips will generate heat during operation, and power transformers will also generate a large amount of heat during load operation. Polysilazane insulation materials can maintain stable insulation performance over a wide temperature range, without softening, decomposition, or significant decrease in insulation performance due to temperature rise. They can adapt to high-temperature baking processes in electronic manufacturing, long-term operation of power equipment, and other high-temperature conditions, ensuring reliable insulation protection for equipment under different temperature conditions.
Adaptation of thermal expansion coefficient: Its thermal expansion coefficient is relatively low, which matches the thermal expansion coefficient of many commonly used materials such as electronic components and metal parts. This prevents stress from being generated between the polysilazane insulation material and adjacent materials due to significant differences in thermal expansion during temperature changes, avoiding problems such as material cracking and peeling caused by stress, further ensuring the integrity and long-term effectiveness of the insulation structure.
Excellent chemical stability
Good moisture resistance: Water vapor in the external environment is one of the important factors affecting the performance of insulation materials. Polysilazane insulation materials have good moisture resistance, which can effectively resist the invasion of water vapor and prevent the electrical insulation performance of the material from deteriorating due to water vapor infiltration, such as avoiding leakage and short circuits. Even after prolonged use in humid environments, reliable insulation can still be maintained, performing well in application scenarios such as marine environments and humid indoor environments.
Strong corrosion resistance: Polysilazane exhibits strong corrosion resistance to various chemical substances that may come into contact, such as acidic and alkaline solutions, organic solvents, etc. In the production process of electronic devices, which may come into contact with chemical cleaning solutions and chemical pollutants in industrial environments, polysilazane insulation materials are not easily corroded and damaged, ensuring the durability of their insulation performance and making them widely applicable to insulation demand scenarios in different chemical environments.
Strong adhesion and good film-forming properties
Firmly attached to substrate: Polysilazane has good adhesion to various common substrates, such as metals (copper, aluminum, etc.), ceramics, glass, and some polymer materials. In practical applications, it can tightly adhere to the surface of these substrates, forming a stable insulation layer that is not easily detached or peeled off, ensuring the reliability of the insulation structure. For example, when insulating various components on a circuit board, it can firmly bond to the surface of the components and the circuit board substrate, playing an effective insulation role.
Easy to form a uniform and dense film layer: It has good film-forming properties and can easily form a continuous, uniform, and dense film layer on the substrate through coating, impregnation, and other processes. This uniform and dense film layer not only provides better insulation performance, but also has a certain protective effect on the substrate, blocking the influence of external environmental factors on the substrate and insulation layer itself, which helps to extend the service life of insulation materials and related equipment.
Processability and adaptability
Formula adjustable: Polysilazane can change its physical and chemical properties by adjusting the formula, such as changing its molecular weight, adding different additives, etc., to adapt to different insulation application scenarios. For example, insulation materials with good flexibility can be made as needed for flexible electronic devices, or insulation materials with high hardness and strength can be made for key parts of large power equipment.
Good process compatibility: It has good compatibility with various common insulation material processing processes, such as spraying, spin coating, casting, etc., making it convenient to carry out processing operations according to different product shapes, sizes, and other requirements in actual production. It is easy to achieve industrial large-scale production, thereby improving its application scope and competitiveness in the insulation material market.
