Glassven Yangzhong Co., Ltd. - Leading Supplier of High-Quality Food-Grade Silica | Innovative R&D, Sustainable Practices & Global Market Reach

Glassven Yangzhong Co., Ltd. is a Sino-foreign joint venture specializing in the R&D and production of silica, established in 2001 with its headquarters located in Yangzhong City, Jiangsu Province, China. As an important global supplier of precipitated silica, its products cover multiple fields such as food, oral care, and industrial coatings, and it has formed significant technological advantages especially in the field of food-grade applications. The following is a detailed analysis from the aspects of technical capabilities, core products, market layout, and compliance certifications:

The company produces silica using the precipitation method, generating amorphous silica through the reaction of sodium silicate and sulfuric acid. The process is mature and the cost is controllable. Its products have a uniform particle size distribution (average particle size of 16 microns) and a specific surface area of up to 150-300 m²/g, showing outstanding performance in the optimization of adsorption properties and fluidity. For example, PIROSIL® PS-300 achieves ultra-fine particle size through grinding process, which can adsorb 3 times its own weight of liquid while maintaining a powder form, and is widely used as a food anti-caking agent and flavor carrier.

The Yangzhong headquarters currently has a production line with an annual output of 15,000 tons of precipitated silica. In 2024, it signed a cooperation agreement with the government of Shaxian District, Sanming City, Fujian Province, to invest in the construction of a 12,000-ton/year food-grade silica production line, which is expected to be put into operation in 2025. The project will adopt intelligent equipment to further improve production efficiency and product consistency.

Although bio-based raw materials are not explicitly mentioned, the company has reduced unit energy consumption by optimizing the wastewater treatment system and energy management. In the 2023 fire incident, its emergency response mechanism effectively controlled the spread of pollution, demonstrating basic capabilities in environmental management.

GELSIL® series: Used in coatings and sealants, it can partially replace titanium dioxide by improving hiding power and UV resistance, thereby reducing production costs. For example, GELSIL GS-300 can maintain stability and leveling in varnishes, and its refractive index of 1.45 has excellent compatibility with resins.

In adhesives and rubber: Precipitated silica, as a reinforcing agent, can enhance the oil resistance of EPDM rubber and reduce the volume expansion rate in synthetic lubricating oil.

The company has passed ISO 9001 quality management system and FSSC 22000 food safety management system certifications. Its products have obtained Kosher and Halal certifications, meeting the needs of global diversified markets. The PIROSIL® series complies with the EU Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with foodstuffs, with heavy metal content controlled below lead ≤ 2ppm and arsenic ≤ 1ppm.

Glassven Yangzhong is a leader in the niche market among global small and medium-sized silica enterprises. Its products are sold to more than 110 countries and regions, with customers including Anhui Wanwei Group (supplying anti-caking agents) and Southeast Asian food processing enterprises. In the domestic toothpaste market, its DENTSIL® series accounts for about 10% of the share, with main customers being regional brands.

Facing the pressure from enterprises such as Evonik and Suocheng Co., Ltd., Glassven Yangzhong needs to make breakthroughs in high-end fields. For example, its fumed silica has not yet been mass-produced, while Solvay has established technical barriers in the field of semiconductor packaging. In addition, the lag in the R&D of bio-based silica may lead to missing opportunities in EU green procurement.

After the Sanming project is put into operation, the company's total food-grade silica production capacity will reach 27,000 tons, focusing on covering the East China and South China markets. At the same time, it will expand the Southeast Asian market through cross-border e-commerce channels, and it is expected that the export proportion will increase to 30% in 2025.

Although the application of bio-based raw materials is not clearly mentioned, the company can learn from Solvay's rice husk ash recycling technology and combine the location advantages of the Sanming project (adjacent to agricultural production areas) to explore renewable raw material substitution and reduce carbon footprint.

Glassven Yangzhong has occupied a place in the food-grade silica market relying on its mature experience in the precipitation process and cost-effective products, especially forming characteristics in the fields of toothpaste and pet food. In the future, it needs to enhance its competitiveness through technological upgrading (such as developing fumed silica products) and sustainable practices (bio-based raw materials), while consolidating its regional market position relying on the capacity expansion of the Sanming base. Despite its small scale, its flexible customized services and international certification system make it irreplaceable in the global supply chain.
