In 2026, during the 25th National “Safety Production Month”, everyone is encouraged to prioritize safety and be capable of responding to emergencies; efforts are also being made to identify and rectify potential risks and hazards. -------------------------------------------------- Recently, Yun Tianhua International Composites received a patent authorization from the **Intellectual Property Office for its invention titled “A glass fiber with extremely low dielectric loss, its preparation method, and applications”. This achievement further strengthens the company’s technological innovation capabilities in the field of glass fibers for high-frequency and high-speed electronics. By optimizing the composition of glass fibers and their preparation process, this patent introduces rare earth oxides in a specific proportion to form a particular structure. Combined with gradient-temperature melting and interface treatment, this approach significantly reduces the dielectric constant and dielectric loss factor of glass fibers. It thus resolves the technical challenge of reconciling the dielectric properties of high-boron glass systems with other requirements such as high insulation performance and low coefficient of thermal expansion. This technological achievement can be applied to fields with high requirements for signal transmission, such as 5G/6G communications and AI servers. It helps enable efficient and stable signal interaction in base station antennas and millimeter-wave devices. Furthermore, its technical advantages can also be applied to areas such as the intelligent electric control systems of new energy vehicles and satellite communication payloads, helping related products achieve more stable and efficient signal transmission and performance output. Against the backdrop of a growing global demand for low-loss, high-speed data transmission, Yuntianhua International Composites has set its strategic goals for the 15th Five-Year Plan period and has secured a series of core patents related to ultra-low dielectric glass formulations. This not only demonstrates its strength in the field of high-end electronic materials but also represents a strategic approach aimed at meeting the needs resulting from technological advancements. To ensure that the outcomes of technological innovation are translated into practical applications in a timely manner, the company has established comprehensive mechanisms for patent identification, strategy development, application, and maintenance, thereby rapidly converting innovative potential into new advantages in market competition and achieving accelerated progress in patent management. Moving forward, Yun Tianhua International Composite Materials will closely align with strategic and industry development trends. It will earnestly uphold its core values of “customer orientation, valuing hardworking individuals, and recognizing value creators.” The company will continue to increase investment in research and development and the commercialization of its innovations, while accelerating the global deployment of its key patents. This will provide robust domestic support for the upstream and downstream industries involved in high-frequency, high-speed copper-clad laminate production, thereby further strengthening China’s ability to maintain self-reliance and control within the next-generation information technology industry chain.
