No need to add anti-aging agent, rubber can be directly in the oil medium, Qingdao University of Science and Technology independently developed a new oil resistant to high pressure rubber - carboxylated nitrile rubber . Recently, the production capacity of this product reached 4,000 tons after the Zibo production in Shandong Province, which not only filled a technical gap in China, but also eased the dependence of high-grade nitrile rubber in China on foreign imports. The ultra-high oil-resistant carboxylated nitrile rubber developed by Qingdao University of Science and Technology is the first quaternary copolymerized nitrile rubber that has been successfully developed in China. Its oil resistance is superior to silicone rubber and fluororubber. It is mainly used for oil seal under high temperature and high pressure environment. At present, China can only produce medium and low-grade carboxylated nitrile rubber. With the rapid economic development in China, the demand for rubber and rubber latex is getting higher and higher, relying heavily on imports. The new rubber developed and put into operation by Qingdao Science and Technology University to a certain extent eased the domestic market demand and broke the monopoly of foreign companies.
