Gold Plated PI Film vs. Aluminum Plated PI Film: Innovative Choice of Advanced Institute Technology

**Gold Plated PI Film vs. Aluminum Plated PI Film: Innovative Choice of Advanced Institute Technology**

In today's rapidly developing high-tech world, the application of new materials is changing our lives at an unprecedented speed. PI (Polyimide) film, as a high-performance material, has emerged in many fields due to its high temperature resistance, chemical corrosion resistance, excellent mechanical strength, and electrical insulation properties. As a leader in new material research and development, Advanced Institute Technology has launched two innovative products - gold-plated PI film and aluminum plated PI film. Although both products are based on PI film, they have their own advantages in performance and application.

###Gilded PI film: shining in the field of electromagnetic shielding and precision

Gold plated PI film is an advanced technology that uses a precise coating process to evenly coat a thin layer of gold film on the surface of PI thin film. This layer of gold film not only improves the conductivity of the PI film, but also endows it with more outstanding electromagnetic shielding performance. In the evaluation of electromagnetic shielding effectiveness, the performance of gold-plated PI film is particularly outstanding. Experimental data shows that the electromagnetic shielding effectiveness (SE) value of gold-plated PI film is over 70dB in the frequency range of 10MHz to 3GHz, far exceeding traditional metal shielding materials.

The high conductivity and excellent electromagnetic shielding performance of gold-plated PI film make it an ideal choice for improving the signal integrity of communication equipment and reducing electromagnetic interference. In 5G and future 6G wireless communication systems, high-frequency communication has become a trend, which puts higher demands on electromagnetic shielding materials. The gold-plated PI film, with its low surface impedance and excellent shielding performance, performs well in complex electromagnetic environments, ensuring the stable operation of communication equipment.

In addition, gold-plated PI film has been widely used in the field of precision optical instruments and sensors due to its unique optical properties and chemical stability. Gold, as a precious metal, is stable in the long run and does not lose its luster. Therefore, gold-plated PI films perform well in optical and laser mirrors, maintaining high reflectivity under extreme conditions.

###Aluminum coated PI film: a leader in optics and high-temperature environments

Aluminum coated PI film is another highly anticipated innovative product of Advanced Institute Technology. By coating a thin layer of aluminum film on the surface of the PI film, the aluminum coated PI film not only improves the conductivity and reflectivity of the material, but also enhances its barrier properties. The high reflectivity of the aluminum plated layer makes the aluminum coated PI film widely used in the fields of optical mirrors and electromagnetic shielding materials.

Compared with gold-plated PI film, aluminum plated PI film has a cost advantage. Aluminum materials are easy to evaporate and the coating process is relatively simple, which makes aluminum coated PI films more affordable in price while maintaining high performance. In the field of optics, the high reflectivity of aluminum coated PI film makes it an ideal choice for optical components such as solar cell backplates and capacitor dielectric films.

In addition, aluminum coated PI film also has good high temperature resistance. Experimental data shows that the conductivity and shielding effectiveness of aluminum coated PI film remain stable in high temperature (≥ 350 ℃) environments. This characteristic makes it possible to apply aluminum coated PI film in high-temperature environments, such as aerospace, automotive manufacturing, and other industrial fields.

###Advanced Institute of Technology: Innovation Leads the Future

Both gold-plated PI film and aluminum plated PI film are high-performance composite materials carefully crafted by advanced research and technology based on market demand and technological innovation. These two products not only inherit the excellent performance of PI film, but also further enhance its conductivity, reflectivity, and barrier properties through coating technology, expanding its application fields.

With the continuous efforts of advanced technology, gold-plated PI film and aluminum coated PI film are gradually becoming ideal choices for electromagnetic shielding, optical mirrors, and high-temperature environments. In the future, with the rapid development of new energy, intelligent manufacturing and other fields, these two products will usher in a broader market space. Advanced Institute Technology will continue to uphold the service concept of "innovation, professionalism, and efficiency", providing customers with better technical services and product solutions, and leading the future development of the new materials field.
