On October 12, 2023, SHMM's newly built 5000 ton/year liquid rubber plant has successfully achieved commercial production – liquid rubber for high-frequency copper clad panels.
The device adopts independently developed technology and its smooth production marks the localization of high-performance liquid rubber in China, which will provide key raw material support for the security of China's information industry.
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 were highly dependent on imports.
SHMM regards liquid rubber as one of the key research directions for high-end new materials. At present, SHMM has developed 4 types, 8 high-end product grades, and production technologies around 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 TPV (thermoplastic vulcanized rubber) and green tires, which will greatly meet the demand for high-end liquid rubber products in the Chinese and international markets.
