At present, the companies that can produce liquid crystal polymer (LCP) films worldwide include Japan's Kuraray, Murata Manufacturing, and Chiyoda. No company in China has the production capacity. Recently, NBJJ New Materials' LCP film was successfully tested in small trials, and LCP film samples were prepared, and mass production is expected next year.
LCP film is a special insulating material, which has the characteristics of low moisture absorption, good chemical resistance, high gas resistance and low dielectric constant. It is also an internationally recognized insulating material essential for 5G signal antennas.
In addition to losses, there are also interference issues. When transmitting at low frequencies, there are few signal lines and there is no interference. When transmitting at high frequencies, several signal lines work at the same time. If they are not insulated with special insulation materials, signals will interfere with each other and various problems will occur. The effect of LCP film is more apparent.
Now the Chinese new material company has completed the LCP thin film test and successfully prepared LCP thin film samples. It is expected that the installation and commissioning of the equipment can be completed next year, and large-scale production with an annual output of 1.4 million square meters.
