Global fumed silica market trend 2023-2026 What is Fumed Silica? by Newsjatujakguide

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.

Fumed silica is a nanometer white powder produced by the hydrolysis of silicon halide at high temperature in an oxyhydrogen flame. It is a kind of amorphous silicon dioxide product, the primary particle size is between 7~40nm, the aggregate particle size is about 200-500 nm, the specific surface area is 100~400m2/g, high purity, and SiO2 content is not less than 99.8%. The vapor phase silica aggregates with untreated surfaces contain a variety of silica hydroxyl groups. 
One is an isolated, undisturbed free hydroxyl group; The other is bonded silyl groups that are linked and form hydrogen bonds to each other. The vapor phase silica aggregates with the untreated surface are aggregates containing multiple -Oh compounds, which can easily form a uniform three-dimensional network structure (hydrogen bond) in the liquid system.  This three-dimensional network structure (hydrogen bond) with external force (shear force, electric force, etc.) will be destroyed, the medium becomes thin, the viscosity drops, and once the external force disappears, the three-dimensional structure (hydrogen bond) will restore itself, the viscosity rises, that is, this thixotropy is reversible.



 
Fumed silica is one of the most important new inorganic materials. It has a small particle size, large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, resistance, and other aspects of specific performance. In addition, its high stability, its reinforcing effect, thickening, and thixotropy, in many fields of unique characteristics make it irreplaceable.
It is widely used in various industries as additives, catalyst carriers, petrochemical, decolorizing agent, matting agent, rubber reinforcing agent, plastic filling agents, ink thickening agents, metal soft polishing agents, insulation and adiabatic filler, advanced daily cosmetic filler, and spraying materials, medicine, environmental protection, and other fields.
 
Fumed silica mainly has two "sex”: hydrophilic and hydrophobic. People can use physical, chemical, and mechanical methods to deal with the fumed silica surface or interface, in order to change its chemical and physical properties of the fumed silica surface, such as surface energy, surface wettability, electrical, adsorption, and reaction characteristics, surface structure and functional groups, etc. Therefore, it can meet the modern new material, new technology, and the needs of the development of new technology. 



Hydrophobic fumed silica applications
Thickening of polar liquids, such as epoxy resins; Silicone elastomer reinforcement; High addition, as in molded products; Good hydrophobicity, improving anticorrosion; Improved dielectric properties, as in cable composites; Powder flow AIDS, such as powder coatings and fire extinguishing agents; Improve scratch resistance in coatings and plastics. 
 
Luoyang Tongrun Nano Technology Co. Ltd. (TRUNNANO) is a trusted global chemical material supplier & manufacturer with over 12-year-experience in providing super high-quality chemicals and Nanomaterials, including silicon powder, nitride powder, graphite powder, zinc sulfide, calcium nitride, 3D printing powder, etc.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.  

The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.  

Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.  

U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.  

The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."  

The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled fumed silica are estimated to be influenced by international political situation changes.
