On October 10, Cao Shuhuai, secretary general of the Special Chemical Materials Committee of the Chinese Chemical Society, said in an interview with reporters that the special chemical products used in Tiangong 1 are only part of special chemical materials independently developed by China. According to him, so far, China has developed 13 special chemical new materials such as special rubber, special engineering plastics, special coatings, special fibers, special adhesives, and special electronic chemicals. These high-tech products basically represent the highest level in their respective fields and provide solid support for the development of China's space and military industries.

Cao Shuhuai said that with the acceleration of the upgrading of China’s armament equipment and the continuous development of the aerospace industry, the requirements for military chemicals are getting higher and higher. A series of special chemical materials with special properties such as super temperature resistance, super thick and super corrosion resistance that have been developed by the chemical industry have been widely applied to military products.

“The special functional material on the surface of the ship can eat the sonar waves emitted by the enemy, making the other party unaware of it, and it can make the ship play a good stealth effect in combat. The surface of the aircraft is sprayed with The absorber containing the vanadium pentoxide component is similar in that it can 'filter out' the radar waves emitted by the enemy's radar so that the radar waves cannot return.The J-20 stealth aircraft that we flew in China recently was painted. This kind of absorber." Cao Shuhuai told reporters.

Cao Shuhuai said that special chemical materials are mainly used in such sensitive areas as aerospace and military. The production technology of many materials abroad will not be transferred to us, and we can only rely on our own research and development. For example, he said that the fuel tank of aircraft engines needs to have high oil resistance, and polysulfide rubber just meets this requirement, but the production of polysulfide rubber requires a raw material called chloroethanol. For a long time we could not produce such products, which seriously affected the performance of our military aircraft. Later, chemical researchers in China passed numerous studies and experienced countless trials. They finally conquered the technical difficulties of this product, broke the monopoly of foreign technology, and met the downstream dyes, pesticides, etc. while ensuring the supply of military raw materials. The needs of the product. "Almost every type of specialty chemical product used in military industry is developed in this way."

Cao Shuhuai emphasized that special chemical materials are characterized by multiple varieties, small batches, and large technical difficulties. The use of such materials in aerospace, military, and other fields is small, and research and development costs are also high. Therefore, we should vigorously expand the application of special chemical materials from military products to civilian products, so that high-end chemical materials benefit the public.
