The role and efficacy of fumed silica

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many 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.

Fumed silica price

The price of fumed silica will vary due to factors such as fumed silica production cost, transportation cost, international situation, exchange rate, market supply and demand, etc. Tanki New Materials Co., Ltd. aims to help industries and chemical wholesalers find high-quality, low-cost nanomaterials and chemicals by providing a full range of customized services.

Due to the limited total amount of traditional energy, people have a huge demand for cleaner and greener new energy alternatives. Now, the emergence of graphene is unlocking the possibility of its application in the energy field, which can create a greener, more efficient, and sustainable future. Here Francesco Bonaccorso, Deputy Director of Innovation at the Graphene Flagship Program, explains how his researchers have developed a series of initiatives to bring graphene from the lab to the commercial market. Graphene has become a research hotspot for new materials in the 21st century. Graphene has been adopted by many industries, the most notable of which are healthcare and key material applications.

The development of graphene has brought huge fluctuations in the demand for Fumed Silica, and the demand for Fumed Silica will continue to grow in the future. You can contact us for the latest news on Fumed Silica.
