People's Daily, Guangzhou, October 13th (Pu Xinyu) According to Sinopec Maoming Branch (hereinafter referred to as "Maoming Petrochemical"), recently, Maoming Petrochemical's 5000 ton/year liquid rubber plant successfully produced qualified products - liquid rubber for high-frequency copper clad panels. The device adopts technology independently developed by Beijing Research Institute of Chemical Industry of China Petroleum and Chemical Corporation. The smooth operation of the device marks the first localization of high-performance liquid rubber in China, achieving a significant breakthrough and providing key raw material support for the security of China's information industry.

During the start-up of the liquid rubber project in the synthetic rubber department of Maoming Petrochemical, the safety officer closely monitored the site and guided the team members to optimize operations to ensure safe and environmentally friendly production of the device.

It is reported that high-frequency copper clad plate is an ultra-low dielectric loss electronic circuit substrate used in high-frequency electronic circuits, and is the most high-end electronic circuit substrate material in the field of copper clad plate. High performance liquid rubber is one of the preferred materials for high-frequency copper clad laminates. The high-frequency copper clad plate prepared from high-performance liquid rubber has characteristics such as low dielectric constant, low dielectric loss, and low water absorption. The signal propagation speed is fast, and the transmission process is not distorted. Due to high technological barriers, key substrates used in high-end fields such as high-frequency copper clad panels in China are highly dependent on imports, which is one of the urgent technical challenges that the petrochemical industry in China needs to overcome.

During the start-up period of the liquid rubber project in the synthetic rubber department of Maoming Petrochemical, the device operators carefully operated to ensure that high-quality products were obtained. Photographed by Chen Liumei

It is understood that currently, Sinopec has successfully developed 4 types, 8 high-end product grades, and production technologies based on high-performance liquid rubber technology, and will gradually achieve large-scale production. This series of high-end new materials will be widely used in 5G high-frequency communication such as mobile phones, computers, automobiles, military industry, aerospace, flexible printing with high environmental requirements for infants, food, cosmetics, as well as high-performance TPVs and green tires, and will meet the demand for high-end liquid rubber products in the domestic market.
