The brief introduction of fumed silica in China

Fume Silica(CAS Number: 112945-52-5) is widely used in silicone rubber, tire, cable compounds and unsaturated polyester resin, adhesives, paint, ink and copier toner, food, cosmetics, playing a role of reinforcing, thickening, anti caking, rheology and thixotropy control, etc.

In recent years, the productivity of fumed silica in China has increased by leaps and bounds. In 2000, the production capacity was only 1100 tons/year, reaching 40,000 tons/year in 2009, and increasing to 86,400 tons/year in 2012. In 2013 Chinese fumed silica production capacity increased to 104,900 tons/year, in 2014, the total production capacity of fumed silica in China was 110, 400 tons/year, accounting for 29.5% of the total global production capacity. However, the proportion of the production capacity of the Chinese local enterprises is not high, the market is almost controlled by several large international companies, such as Cabot, Wacker, Degussa, Tokuyama, etc. In 2014, there was about 26 production enterprises of fumed silica in China, the total output was 58, 800 tons, while the part of the output of the 4 foreign joint ventures was 470,00 tons.

The import and export volume of fumed silica in China in 2014. 

Import Volume  Year on year growth rate Export Volume  Year-on-year growth rate
9,000 Tons                    0% 14,000 Tons                 -6.7% 

The fumed silica produced in China had been exported to many countries in 2014, including Korea, USA, Japan, Indonesia, Iran., etc. The volume exported to Korea, USA, Japan accounted for 57.9% of the total volume be exported. 

The total consumption volume of fumed silica in China was 54, 400 tons in 2014, year-on-year growth rate was 11%, it is expected that the total production capacity of fumed silica in China will reach 98,000 tons, the total consumption volume will reach 88,000 tons. The average growth rate of the consumption volume is expected to be 10.3% during 2014~2019. 

Although the fumed silica industry in China has developed rapidly in recent years, there are still some problems to be solved: 

1. The industry concentration is low, the local manufacturers are numerous, but the average production capacity is small, there is still a big gap compared with those world famous manufacturers. 

2. The product structure is unreasonable, most of the products are middle or low grade, the proportion of the hydrophobic silica and fumed silica with high specific surface is still limited. 

3. The production technology of fumed silica in China is still relatively outdated.
