Recently, Shandong Haochuang New Materials Technology Co., Ltd. has made significant progress in the research and development of silica products. After years of technical efforts, the company has successfully optimized the production processes of fumed silica and precipitated silica. The performance of its core products, hcsil-150 and hcsil-380, has been significantly improved, with some indicators reaching the leading level in the industry.

Since its establishment in 2018, Shandong Haochuang New Materials Technology Co., Ltd. has been focusing on the research, development and sales of new materials, among which silica is one of its core businesses. Fumed silica, with its high specific surface area and good reinforcing properties, is widely used in high-end fields such as silicone rubber, adhesives and coatings; precipitated silica, due to its cost advantage and applicability, has strong demand in industries such as rubber (especially tire manufacturing), feed and pesticides. As the star fumed silica products of the company, hcsil-150 and hcsil-380 have attracted much attention in the market.

In this technical breakthrough, the improvements of hcsil-150 andHCSIL-380 focus on purity and dispersion stability. HCSIL-150 is a hydrophilic fumed silica with a specific surface area of about 150 m²/g. Through independently developed advanced purification technology, Haochuang Materials has raised its purity to a new height and significantly reduced impurity content. This enables it to more effectively enhance the hardness, tensile strength, tear resistance and wear resistance of products in fields such as high-temperature vulcanized (HTV) silicone rubber, while also improving their anti-aging performance and effectively extending the service life of products. In adhesives and sealants, HCSIL-150 has improved rheological and mechanical properties, solving the problem of sagging and dripping during the construction of sealants and preventing spray collapse.

HCSIL-380 is a hydrophilic fumed silica with a specific surface area of about 400 m²/g, featuring high specific surface area and high surface activity. After process optimization, while its purity is improved, the optimization of surface modification process makes it disperse more uniformly in coating systems. In liquid silicone rubber (LSR),HCSIL-380 maintains high transparency, effectively improving tensile strength and tear strength, enhancing mechanical properties, adjusting the viscosity of rubber compounds, improving processing performance, without changing the original color of rubber compounds, maintaining ideal transparency, and also improving high-temperature resistance and anti-aging performance. In the construction process of coatings and paints, it prevents sagging and thick edge phenomena, improving construction efficiency.

For precipitated silica, the R&D team has focused on improving its reinforcing effect and particle size uniformity. The improved precipitated silica has performed prominently in the rubber industry. When added as a reinforcing agent to tire rubber compounds, it can significantly improve the tensile strength, wear resistance and wet skid resistance of rubber, while reducing rolling resistance, helping to improve theendurance capacity of new energy vehicles. In addition, the more uniform particle size distribution enables it to more stably adsorb active ingredients in feed carrier applications, improving feed efficacy.A responsible person of Haochuang Materials said: "HCSIL-150,HCSIL-380 fumed silica and precipitated silica are important product lines of the company. This technical breakthrough is the result of the company's long-term commitment to innovation investment. In the future, we will continue to deepen research and development for the application scenarios of different models of products to provide customers with better solutions."

With the application of new technologies, Shandong Haochuang Materials plans to gradually expand the production scale of the two types of silica to meet the growing market demand for high-performance products. This breakthrough of the company not only injects new impetus into its own development, but also is expected to promote the technological progress and industrial upgrading of the domestic silica industry.
