In the wave of global industrial acceleration towards green and intelligent transformation, organic silicon, a "industrial monosodium glutamate" that combines inorganic material temperature resistance and organic material flexibility, is breaking through traditional application boundaries and shining brightly in strategic emerging fields such as new energy, electronic information, and biomedicine, becoming a key material for promoting high-quality development of the manufacturing industry.
New energy track: Organic silicon 'sticks' to trillion dollar market
With the global photovoltaic installed capacity growing at an average annual rate of 30%, organic silicon materials have become the "invisible guardians" to ensure the 25 year service life of photovoltaic modules. In the packaging process of photovoltaic modules, organic silicone adhesive, with excellent weather resistance, transparency, and insulation properties, can effectively resist extreme environmental erosion such as ultraviolet radiation, high temperature, and high humidity. The "two-component additive silicone" developed by leading domestic enterprise Hesheng Silicon Industry has increased its tensile strength to 3.5MPa and adhesive strength to 2.8MPa, improving the lamination efficiency of photovoltaic modules by 15%. It has been applied in the world's largest single photovoltaic power plant project.
In the field of new energy vehicles, organic silicon materials are restructuring the battery safety system. In view of the problem of thermal runaway of power battery, the composite scheme of "aerogel felt+silicone potting adhesive" developed by Huitian New Material can extend the thermal diffusion time of battery pack to more than 30 minutes, far exceeding the national standard of 5 minutes. At the same time, the application of silicone thermal conductive gel in the electric motor and electronic control system has improved the heat dissipation efficiency by 40%, helping the new energy vehicle's range exceed 1000 kilometers.
In the field of electronic information, organic silicon "shapes" future technology
In the construction of 5G communication base stations, organic silicon thermal conductive gaskets have become the core material to solve the bottleneck of high-frequency signal heat dissipation. The "low volatility, high thermal conductivity" silicone gasket launched by Wacker Chemie has a thermal conductivity coefficient of 8W/m · K, which can meet the heat dissipation needs of equipment in the frequency band above 6GHz. It has been widely used in 5G base stations of enterprises such as Huawei and Ericsson.
The breakthrough of flexible display technology cannot be separated from the support of organic silicon. The "self-healing silicone protective film" developed by Dow Corning introduces a dynamic covalent bond structure, which can automatically repair microcracks after 100000 screen bends, extending the service life of foldable phones by three times. This material has passed rigorous testing on Samsung Galaxy Z Fold series models, ushering in a new era of consumer electronics.
Biopharmaceuticals: Organic Silicon Weaves Health Defense Line
In the field of medical implants, silicone materials exhibit unique biocompatibility. The "long-acting antibacterial silicone catheter" developed by Braun Medical has reduced the infection rate related to the catheter by 76% through surface grafting of quaternary ammonium salt groups, and has been clinically applied in 500 tertiary hospitals worldwide. In terms of drug delivery system, the "mesoporous organosilicon nanocarrier" developed by the Institute of Process Engineering, Chinese Academy of Sciences, can achieve the precise release of anticancer drugs in tumor tissue, and animal experiments show that the tumor inhibition rate has increased to 89%.
From photovoltaic adhesive to thermal conductive gel, from flexible screen to nano carrier, the silicone industry is reshaping the global material pattern at an annual growth rate of 12%. With the deepening of the "dual carbon" target and the acceleration of domestic substitution, Chinese organic silicon enterprises have mastered 80% of the global industrial silicon production capacity and 45% of the organic silicon monomer production capacity. This material revolution triggered by organosilicon is injecting tremendous momentum into sustainable human development.
