In recent years, it has provided important product technology for the research and development of polymer synthetic materials in China, Environmental protection resin, nano chemical industry and special engineering materials have mature technical experience. In addition to being proud of this technology at home and abroad, it has also been discussed and purchased by many foreign enterprises. Among them, rubber compound has become one of the key synthetic technologies.

Synthesis technology of silica gel

At first, foreign enterprises paid attention to Taiwan health chemical industry, Hong Kong Integrated Optoelectronics, Poland National Industrial Research Institute and Korea's KCC, Yiyou, Hailong and other large listed companies from China to purchase rubber mixing and raw rubber synthesis technology. In the past 20 years, Chenguang College's raw rubber synthesis technology has been transferred to many enterprises in the country, and more than 10 times want to transfer it to foreign enterprises!

Among them, Dow Corning company of the United States also decided to purchase the rubber compound synthesis manufacturing technology from Chenguang Institute, but the transaction was not successful due to the high asking price of Chenguang Institute. In a word, the industrial synthesis of high temperature vulcanized silicone rubber products in China started from the continuous chemical process of intermittent dehydration continuous polymerization and continuous low molecular weight removal in the Research Institute of Jihua company, the successful application of static mixer in Chenguang Institute, and the improvement of batch polymerization process, which has made great progress in the past ten years. The production technology of raw rubber has reached the world advanced level and attracted the attention of the industry. For this reason, the Chinese government awarded Wang Weiliang, the inventor of continuous process silicone rubber production technology, the second prize of national science and Technology Progress Award in 2001.

 

The above situation is enough to show that China is no inferior to multinational companies in the production process of heat vulcanized methyl vinyl silicone rubber and the manufacturing quality of silica gel products. In recent years, it can be concluded from China's silica gel manufacturers that China's import and export of silicone rubber has accounted for more than 30% of the global market share, while the hot vulcanized silicone rubber of other multinational companies is actually produced by many private enterprises in China.
