International leader in liquid rubber for 5G high frequency copper clad laminates

Sinochem News News on September 1, Beijing Research Institute of Chemical Industry announced that its self-developed liquid rubber technology and process package for high-frequency copper clad laminates for 5G communications have passed the evaluation organized by the Ministry of Science and Technology of China Petrochemical, and the overall technology has reached the international leading level

High-frequency copper clad laminates are mainly used for printed circuit boards and are key components of 5G communications.

At present, only a handful of countries in the world have 5G communication high-frequency copper clad laminate liquid rubber production technology, which has seriously affected the security of China's 5G industry and information technology, and restricted the high-quality development of the 5G industry

On the basis of years of rubber technology development, the project team of the Yanshan Branch of Beijing Institute of Chemical Technology has thoroughly studied the essential characteristics of 5G high-frequency copper clad laminate cross-linking and curing matrix materials.

The project team systematically studied the structure-effect relationship between the microstructure of liquid rubber and the performance of copper clad laminates, revealed the internal relationship between the molecular structure of rubber and the mechanical properties, dielectric properties, and heat resistance of copper clad laminates, and refined the microscopic "gene fragments" of liquid rubber.

In addition, the project team also combined the polymerization process to tailor a high-efficiency product purification process to overcome the key technical problems of low dielectric constant and low dielectric loss of liquid rubber for 5G high-frequency communication, and to achieve the complete content of metal ions in the liquid rubber.

Based on a series of major innovations such as molecular structure design and precise control technology, they have systematically solved a series of key scientific problems related to liquid rubber for 5G high-frequency copper clad laminates.

The green and efficient polymerization process innovatively developed by the project team reduces the emission of "three wastes", anchors the dual-carbon goal and implements green development
