At present, the technology of silicone rubber products is a significant development trend, with the development of 0.5 ~ 0.8mm particle size based on all kinds of silicone rubber products in China, with the development of 1--15μ m particle size of silica gel in Europe and the United States and Japan has made great progress. The differences in morphology and properties of silica gel and silica gel are the direct driving force for the development of diversified applications. Although China's enterprises to actively carry out technical research and development, but R & D investment is less than 3% of sales, and the United States as the representative of the developed countries generally reached 5% or higher, if converted into absolute value, the gap is very obvious.
Basic silica gel in addition to the traditional desiccant application, in the petrochemical and other key areas also have a good performance, but also extended to some new areas, so the current technology research and development of the foundation is the focus of our country, the technology level and foreign companies compared favorably. In recent years, the basis of silica gel export volume continued to increase, foreign investors in China's basic silica gel, a part of the direct application, a part of the processing into powder silica gel.
Export growth has made foreign companies rely on our country's basic silicone rubber products, and the improvement of the professional division of labor.
Silica gel by resources, environment and national policies, in recent years, Europe and America, Japan and South Korea enterprises focus on the development of silica gel, silica gel, silica gel is less, the environment has little effect on the environment, two is a high added value; three is advanced technology, easy to keep secret, occupy the high-end, help to improve the core competitiveness of enterprises. Enterprises in these countries in the world of technology is in the leading level, professional advantages are very obvious. Silica gel for the production of Chinese enterprises have also made efforts, but no matter the capital investment or technical level with Europe and America, Japan and South Korea and other countries have a big gap.
