Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of Fumed Silica.

Overview of Fumed Silica

Fumed silica (CAS: 112945-52-5), also known as fumed silica because it is produced by fusing tiny droplets of amorphous silica into branched, chained, Three-dimensional secondary particles and then condensed into tertiary particles. The resulting powder has very low bulk density and high surface area. When used as a thickener or reinforcing filler, its three-dimensional structure leads to increased viscosity, thixotropic behavior. It is an amorphous silica product, the primary particle size is between 7~40nm, the aggregate particle size is about 200~500nm, the specific surface area is 100~400m2/g, the purity is high, and the SiO2 content is not less than 99.8%. Untreated fumed silica aggregates contain a variety of silanol groups.

Application of Fumed Silica

Fumed silica is used in powders as a general purpose thickener and anti-caking agent (free-flowing agent). Like silica gel, it can be used as a desiccant. It is used in cosmetics due to its light diffusing properties. Fumed silica is used as a lightweight abrasive in products such as toothpaste. Other uses include fillers in silicone elastomers and viscosity modifiers in paints, coatings, printing inks, adhesives and unsaturated polyester resins.

Applications in Paints and Coatings

Fumed silica is widely used in paints and coatings as a rheological additive, which can effectively prevent the sedimentation and delamination of pigments and fillers, improve the weather resistance and scratch resistance of coatings, and improve the bonding strength of coatings and substrates. .

Applications in Fertilizers and Feeds

Fumed silica has strong adsorption and hygroscopicity, which can promote the free flow of powders such as fertilizers and feeds, facilitate the transportation and storage of powders, and prevent them from getting wet.

Application in pesticides and medicine

Fumed silica has the characteristics of small particle size, large specific surface area, strong adsorption performance and easy suspension. It can absorb a large number of water molecules in the water, expand into extremely fine particles, and form a stable suspension. Taking advantage of these properties, it can be used as a carrier for pesticide wettable powder, granules, and water-dispersible granules, as a dispersant and thickener for suspending agents; Carriers and excipients to achieve the purpose of prolonging drug efficacy.

Applications in Adhesives and Sealants

The excellent reinforcing, thickening and thixotropic properties of fumed silica can prevent the precipitation of adhesives and sealants during storage and sag during curing, improving their tear strength and bond strength.

The coronavirus (COVID-19) pandemic not only had a significant impact on public health, it also severely affected one of the linchpins of the global economy – the tourism industry. As many countries introduced curfews and travel restrictions to contain the spread of the virus, travel across the world significantly declined from early 2020 onwards. The financial repercussions of the coronavirus have already begun to manifest themselves within the tourism industry. In 2020, global revenue from the travel and tourism industry was estimated to drop from a forecasted 711.94 billion U.S. dollars to 568.6 billion U.S. dollars, representing a decrease of over 20 percent. The region predicted to see the highest decline in revenue was Europe, decreasing from 211.97 billion U.S. dollars in 2019 to roughly 124 billion U.S. dollars in 2020.
The downturn in tourism has caused the recession, and the weakening of the economy has also affected the market demand for Fumed Silica. Recently, however, the demand for Fumed Silica has increased, so contact us for the latest news on Fumed Silica.
