Nowadays, the complexity and diversity of electronic devices continue to increase, and many devices require stable operation in high-temperature environments. Whether in smartphones, computer hardware, or the aerospace industry, high temperatures can have an impact on the performance and lifespan of electronic components. Therefore, choosing appropriate protective materials is crucial. PI protective film (polyimide protective film) plays a crucial role as a high-performance material in these high-temperature environments. It not only effectively protects devices from high temperatures, but also provides excellent electrical insulation and chemical stability, making it the preferred material for electronic devices in high-temperature environments.

One of the most prominent characteristics of PI protective film is its excellent high temperature resistance. The molecular structure of polyimide (PI) material endows it with strong thermal stability, enabling it to maintain its physical properties in high temperature environments. Compared with traditional plastic materials, PI film has a significantly wider temperature resistance range, generally able to withstand high temperatures of 200 ° C to 300 ° C, and even some special varieties of PI film can withstand higher temperatures. Therefore, it is particularly suitable for electronic devices that operate at high temperatures.

Electronic products often experience temperature fluctuations during operation, especially in the fields of high-performance computing, automotive electronics, smartphones, and consumer electronics. For example, in smartphones and laptops, processors and other components generate a large amount of heat, and during long-term high load operation, the internal temperature of the device can rise to 70 ° C or even higher. In this environment, traditional materials are prone to deformation, aging, or failure, and cannot effectively protect electronic components. And PI protective film can work stably for a long time, even in extreme high temperature environments, maintaining stable physical and chemical properties to protect electronic components from damage.

In addition to high temperature resistance, PI protective film also has excellent chemical stability. In the working environment of electronic devices, especially in the fields of industry, automotive electronics, aerospace, etc., various chemical substances such as acids, bases, solvents, etc. are often encountered for corrosion. PI film has strong resistance to these chemicals and can effectively prevent external corrosive substances from damaging electronic components, thereby improving the service life and stability of equipment.

In the field of semiconductor packaging, electronic components often need to operate in acidic or alkaline environments. Traditional protective films may degrade due to chemical reactions, leading to the failure of the protective layer. The PI protective film is not only resistant to high temperatures, but can also withstand these harsh chemical environments, ensuring that the components are not affected by external factors for a long time and maintain good working conditions. This chemical stability makes PI film an essential protective material for electronic devices in high temperature and chemical environments.
