Silica gel is a kind of spatial three-dimensional network structure of amorphous Sio2 product is silicate polymer. 4t  can produce 1t sodium silicate gel. Its molecular formula is: SiOx "xH2O, glassy appearance is transparent or translucent body block or spherical body. By chemically inert silica, surface area and internal porosity, and a strong adsorption capacity for water, Drunk , benzene, gasoline and other organic solvents or other gases such as S0r have good adsorption in the foreign application of silicon into almost all walks of life, as an important inorganic chemical products occupy in the national life position can not be ignored. production of silica gel products in China started late, where A, B-type spherical silica gel in Qingdao in 1993 and developed a chemical industrial production, packed with silica gel to fill the domestic blank. At present, annual production reached 200 kt silica gel around and become exporting countries, including rising star - Sinochem Shandong Xin, sodium silicate because of its many years of production experience, is now on a silica gel production lines, annual output of silica gel 15,000 tons exported in Shandong silica gel backbone. At present, most of the silica gel product is inexpensive desiccant silica gel in recent years, China's high value-added silica and aerogels powder has enhanced its development, these products can Matting agent for paints, plastics and other anti-adhesive and catalyst.

In recent years, silica gel industry has shown rapid development momentum, specialization tends to refinement and technological progress to promote applications continue to expand in North America, European Union, China, Japan, Korea and Southeast Asia are the main R & D and market location, concentration of production capacity, Features obvious. China is still low-end products, nearly half of European companies belonging to multinational companies, according to their geography, population, resources, industry, distribution, trends and market demand, the world is divided into several regional markets in more than 50 major countries R & D centers or cities, branches, representative offices or production plants, their products and services through them to neighboring countries, regional and urban expansion. Korean and Japanese companies followed the steps U.S. and European companies, has expanded into Southeast Asia. Our company's products have been exported to the world's 30 countries and regions, expanding the product in overseas markets, increased market coverage, but has yet to set up offices in overseas funding, and non-branded products exports accounted for more than 50%, not conducive to the improvement of the competitiveness of the future; silica gel-based exports accounted for more than 90% of the foreign market influence is small. 

Europe, Japan and South Korea strong corporate brand awareness, competition, a focus on the high-end products, powder silica, functionalized silica gel is the focus of competition between them, while the silica gel based-focus of competition is still in China.
