Electrical grade silica powder is an active silica powder. It is used for electrical products epoxy resin insulation seal packing. It can not only greatly increase the amount of fill, it is more important to reduce viscosity of the mixture system. It can also improve the processing performance, improve mixture permeability of thigh-voltage electrical coils, reduce shrinkage in the expansion coefficient of cured and curing process, feed the mixture between the coils heat sheets and improve curing heat, electricity or mechanical properties.

At the international level, the annual global demand for silicon powder are 100,000 tons. Gold production epoxy compound rely on imports from the source 30.000, annual demand for flint dust, the U.S. is the source of the required 20 000 flint smoke microsilica in Korea more than 10,000 sources of annual needs.

The mass of stone dust in China in the crystal powder of high purity liquid rock 300 -1000 20% -35% will continue to grow, and increases the sensitivity, the network continues to grow and expand the scope the problem. In 2001 18000 was the source of the time, 48 000 tonnes imported in 2004, including 12,000 78,000 imported from the source of the total volume, the total number in 2012 was 25,000 tonnes, should exceed the total amount of 100,000 was the source of the first half of the year. 20 000 is the source of the annual demand of microsilica is a high-tech sector.

December 15 to 30 is the source of the stone dust is obtained, by 2010 China's demand for electronic products, demand for crystalline rock dust, the source of the annual demand is expected to 700,000, rock, country, China, the annual demand will increase from 30,000 sources microsilica, a broad market potential. Flint is a steam imports more expensive. The rapid development of China's accession to the WTO, as the IT industry in China, the electronic packaging industry in China is moving more slowly.

China will become a great country. The demand in the world market is growing significantly. Such a powder, 300 mesh flint, flint powder, but the price is thousands of miles rovisions, price targets for the short-purity, high value of the micronized 100,000 10,000 yuan / ton at the top, only 600 yuan / ton and 200 yuan / source of nano-scale melting of the updated pink.

Chinese metal powder supplier has successfully developed an electronic system capable of high purity fine rock dust and more. This material is produced in electronic market expectations of interest rates. Flint powder of high purity and packaging material along LSI electronics, which is the main raw material for the substrate or a chip and the end portions of the epoxy cement was built in the message list of neighbors. Ultra-fine stone powder, the coefficient of expansion of the epoxy resin is mixed with the substrate. Microsilica base in a deep expansion coefficient is closer to the line expansion illegal microns to avoid the loss coefficients of expansion of silicon. Therefore, the purity of the stone dust and particle size distribution is strictly for excellence.

The silica powder has an attractive market prospect and broad space for development. With the development of high-tech, the requirements for silica powder materials become higher and higher. The companies can adjust the product structure according to needs of the market. They can develop deep-processed products and improve the competitiveness of enterprises. But these must have an essential premise --- scientifically and technological innovation. Only by relying on technology and developing high-tech products, the market space will be continue expanded and forms a virtuous cycle.Source:http://www.mhcmp.com
