Simply analyze the future trend of the silicone products industry


At present, the technology of silica gel products shows a clear development trend of specialized division of labor. The basic silica gel with a particle diameter of 0.5 to 0.8 mm is developing rapidly in China, and fine powder silica gel with a particle diameter of 1 to 15 μm is obtained in Europe, America, Japan and South Korea. Great progress. The difference in the shape and performance of basic silica gel and micro-powder silica gel has become a direct driving force for the development of diverse applications. Although Chinese enterprises actively carry out technological R & D, R & D investment is less than 3% of sales, while developed countries represented by the United States generally reach more than 5% or even higher. If converted into absolute values, the gap is very obvious.

In addition to the traditional desiccant application, basic silica gel also has good performance in key fields such as petrochemicals, and it has also expanded into some emerging fields. Therefore, the current technical research and development of basic silica gel is the focus of Chinese enterprises, and the technical level is comparable to foreign companies. No worse than. In recent years, the export volume of basic silica gel has continued to increase. Foreigners have purchased basic silica gel in China, part of which is directly applied, and part is processed into fine powder silica gel.

Export growth has increased the dependence of foreign companies on China's basic silica gel, and Shenzhen Weijiamei Rubber and Plastic Electronics has further increased the degree of professional division of labor.

Micropowder silica gel is affected by resources, environment and national policies. In recent years, companies in Europe, America, Japan and South Korea have shifted the focus of development from basic silica gel to micropowder silica gel. First, micropowder silica gel consumes less resources and has little impact on the environment; second, it has high added value; The third is advanced technology, easy to keep secret, and occupy high-end, which helps to improve the core competitiveness of enterprises. Enterprises in these countries are at the world's leading level in technology, and their professional advantages are obvious. For the production of micro-powder silica gel, Chinese enterprises have also made efforts, but no matter the capital investment or technical level, there is a big gap with Europe, the United States, Japan and South Korea and other countries.
