JSLR Silicon Materials Technology Group is mainly engaged in the R&D, production and sales of silicon powder. The main products include crystalline silicon powder, molten silicon powder and spherical silicon powder. The silicon powder products have high heat resistance, high insulation, low linear expansion coefficient and thermal conductivity. It is a kind of advanced inorganic non-metallic material with excellent performance. It is widely used in copper clad laminates for electronic circuits, epoxy molding compounds for chip packaging, electrical insulating materials, adhesives, ceramics, paints and other fields. Electronics, automotive industry, aerospace, wind power, defense military industry and other industries.
The technology of spherical silicon micropowder is relatively difficult, and it has been monopolized by foreign manufacturers for a long time. The company has been actively researching and exploring the process technology of preparing spherical silicon micropowders by physical methods from 2006, and achieved a technological breakthrough in the field of high-temperature flame spheronization by 2010, successfully mastering the anti-sticking wall and anti-coking of spherical silicon micropowders prepared by flame method at high temperature The key process technologies such as anti-cohesion and particle size control have reached the international level. At present, they have passed the verification of downstream customers. In the first half of 2019, they supplied the global copper clad laminate manufacturer Shengyi Technology.
Through more than ten years of technical research and industrial construction, the company successfully implemented the "large-scale integrated circuit and IC substrate spherical silicon powder industrialization project", breaking the monopoly of spherical silicon powder products in Japan and other countries.
In terms of copper clad laminates, the company's spherical silicon micropowder is in the phase of accelerated volume in the field of copper clad laminates. In the first half of 2019, the spherical silicon micropowder's proportion in the sales of copper clad laminates rapidly increased to 10.88%, about 325 tons. my country's CCL production has accounted for more than 70% of the world's total, and the production capacity continues to be transferred to China, but spherical silicon micropowder is still in the initial stage of heavy volume, and there is a huge domestic replacement space.
At present, the only domestic manufacturers that have passed product verification and can continuously and stably supply spherical high-end silicon fine powder for 5G high-frequency high-speed copper clad laminates are Lianrui New Materials. There are only two Japanese companies, Yaduma and Denka Co., Ltd. abroad.
The company has an excellent customer structure. Jinan Guoji, Taiyao Technology, Korea Doosan Group and other companies have established supply relationships. The increase in demand for spherical powder by CCL companies such as Shengyi Technology, Lianmao Electronics, and Nanya Electronics is the core driver of the company's performance growth.
