Domestic break through! GESEESIL 200: A cost-effective “national treasure” in the field of fumed silica, a powerful substitute for AEROSIL 200!

Say goodbye to reliance on imports! GESEESIL 200: A high-performance gas-phase silica substitute made in China, with a specific surface area of 200 comparable to AEROSIL 200!

Dear friends in the materials industry, hello!

In the field of high-performance materials, fumed silica (Fumed Silica) plays an indispensable role due to its unique properties such as thickening, thixotropic, anti-settling, and reinforcing effects. When it comes to benchmarks in this field, many people immediately think of Evonik's AEROSIL® 200 — this classic product with a specific surface area of 200 m²/g has long dominated the market thanks to its outstanding performance and stability.  

However, the high prices of imported brands, potential supply chain risks, and the growing demand for domestic alternatives have led more and more users to seek reliable alternatives with comparable performance and better cost-effectiveness. Today, we will delve into a highly anticipated domestic newcomer—GESEESIL 200 pyrogenic silica from GESEE New Materials Co., Ltd.—to see if it can truly take on the role of a viable alternative to AEROSIL 200! Say goodbye to import dependency! GESEESIL 200: The domestic pioneer of high-performance vapor-phase silica, with a specific surface area of 200 matching AEROSIL 200!

Why 200 m²/g?  

One of the core performance indicators of fumed silica is specific surface area (SSA). A higher specific surface area indicates finer particles and more active surface sites, typically resulting in more pronounced thickening, thixotropic, and reinforcing effects. The value of 200 m²/g is a significant threshold:

• Balanced performance: It provides significant thickening and thixotropic effects without excessively increasing system viscosity or causing processing difficulties, making it highly versatile.
• Mature application: It serves as a foundational reference point for numerous established formulations (particularly in silicone rubber, coatings, inks, adhesives, sealants, cosmetics, pharmaceuticals, and other fields).
• Industry benchmark: The success of AEROSIL 200 has established it as the de facto industry standard, with many formulation developments using it as a reference.

Therefore, a domestically produced fumed silica that consistently achieves a specific surface area of 200 m²/g holds undeniable strategic significance and market potential. Domestic breakthrough! GESEE 200: A high-performance, cost-effective “Made in China” solution in the fumed silica sector, and a strong alternative to AEROSIL 200!

TECHNICAL DATA

Core advantages of the alternative: cost-effectiveness and supply security

Performance benchmarking is the foundation, but GESEESIL 200’s core competitiveness as an alternative lies in:

• Significant price advantage: This is the most direct and appealing aspect of domestic substitution. While ensuring comparable performance, GESEESIL 200 typically offers a more competitive price, helping businesses effectively reduce raw material costs and enhance product market competitiveness.
• Stable and reliable domestic supply: GESEE possesses advanced production facilities and a comprehensive quality control system domestically, ensuring stable and timely localized supply. This reduces reliance on imported supply chains, mitigates potential logistics and geopolitical risks, and typically results in shorter delivery cycles.
• Localized technical support and services: GESEE's technical support team is closely aligned with the domestic market and users, providing faster response times and solutions tailored to local needs.  

Does “equivalent” mean exactly the same?

We need to view the term “equivalent” objectively.

Performance: In terms of core physical and chemical properties and application performance, GESEESIL 200 has already performed exceptionally well, capable of meeting the requirements of most formulations that previously used AEROSIL 200. Direct replacement testing is feasible in most cases and yields good results.

Minor differences: Minor differences in production processes among different manufacturers may result in slight variations in product dispersion, oil absorption value, surface hydroxyl distribution, and batch consistency. These differences may require minor adjustments in certain extremely demanding application scenarios or formulations that are highly sensitive to process conditions.

Brand recognition and historical legacy: AEROSIL has a strong brand influence and a long history of accumulated application data. GESEE, as a strong challenger, is rapidly building its own reputation and database.

How to evaluate GESEESIL 200?

If you are currently using AEROSIL 200 and seeking to reduce costs or secure your supply chain, we strongly recommend conducting small-scale or pilot-scale validation tests:

1. Contact GESEE: Request GESEE 200 samples and detailed technical documentation.
2. Parallel testing: Replace AEROSIL 200 with an equal amount of GESEESIL 200 in your existing formulation and conduct comprehensive performance testing (rheology, mechanical properties, storage stability, processing performance, etc.).  
3. Evaluation results: Compare test data and application performance. Most users report a smooth replacement process with performance meeting requirements.  
4. Cost calculation: Calculate the cost savings achieved through the replacement.
