Phenyl silicone oil: China's breakthrough battle for aerospace materials
In 2023, the localization rate of phenyl silicone oil in China jumped from 32% to 68%, which is a dual breakthrough of technological breakthroughs and industrial upgrading. The gradient polymerization technology developed by Zhonglan Chengguang precisely controls the chain segment distribution of phenyl and methyl groups, achieving a batch stability of 99.8%, reducing energy consumption by 40% in continuous production, and reducing costs by 35% compared to imported products.


At the Antarctic research station, the 250-30 phenyl silicone oil from Shanghai Resin Factory achieved a cold start time of ≤ 3 seconds at -65 ℃, and the hydraulic system failure rate decreased by 75%; In the commercial aerospace field, Blue Arrow Aerospace's "Zhuque-3" reusable rocket uses domestically produced high phenyl silicone oil as a thermal protection coating, which has withstood 30 ground ignition tests with a coating loss rate of less than 0.1%. From formulating 12 national/industry standards to establishing the world's first performance database, China's phenyl silicone oil industry is shifting from "following" to "leading", providing a "Chinese solution" for extreme environmental materials worldwide.
