Communication equipment and electronics manufacturer Shenzhen Xingshengdi New Materials Co., Ltd. uses BASF plastic additives to produce 5G base stations for major international telecommunications companies. With the help of BASF Tinuvin® 360 light stabilizer, 5G outdoor base stations can resist aging and degradation caused by strong sunlight, thereby maintaining stable operation and extending service life.
Base stations use radio waves to relay communications between mobile devices and the core network, and are usually installed outside buildings. These base stations are generally made of polycarbonate and undergo various degradation reactions under direct sunlight. Therefore, it is necessary to perform light stabilization treatment.
Tinuvin® 360 can be added to polycarbonate resins at the production stage, especially to meet the processing and aging conditions of high load, very low volatility and good compatibility. The low volatility of this material helps reduce die fouling and prolong operation time, which makes the process more stable, shortens production time, and reduces maintenance costs.
In addition, Tinuvin 360, which is used in terminal electronics, has strong UV absorption properties: it absorbs UV light and converts it into heat to release it, protecting products under direct sunlight from UV rays.
Hermann Althoff, senior vice president of BASF's Performance Chemicals business unit in Asia Pacific, said: "By optimizing production processes, Tinuvin 360 can create higher value, thereby increasing productivity and profitability. We can also use it to customize mechanical properties that are superior, More weather-resistant plastic equipment. "
Xu Dixiu, general manager of Shenzhen Xingshengdi New Materials Co., Ltd. said, "In the past, outdoor base stations were made of metal materials. Now, we use small and lightweight plastic packages to provide the size, weight and power performance required for various commercial applications. . This not only optimizes system performance, but also makes prices more competitive. "
BASF has conducted in-depth research on the stability of plastic products under UV irradiation in the laboratory. Chemists perform various application tests in dedicated laboratories and application centers to analyze and study the degradation mechanism of plastics. These research results will be directly applied to the development of hindered amine light stabilizers and ultraviolet absorbers.
According to the relevant requirements of ISO 4892-2: 2013, Tinuvin 360 has passed the test of the weathering test device in a simulated environment. This international standard specifies a test method for exposing a sample to a humid environment and exposed to a xenon arc lamp, in order to simulate the aging reaction (temperature and humidity) of a polymer in the actual environment of use, that is, exposure to sunlight. The data from the accelerated aging test was then used to evaluate the durability of the polymer in different application environments.
