The chemical name is ethyl perfluoroisobutyl ether: CAS 163702-06-5.
It is a high-performance, environmentally friendly electronic fluorinated fluid, commonly known as HFE-7200 or Novec 7200. It is a colorless and transparent liquid at room temperature, featuring low viscosity, low surface tension, non-flammability, good electrical insulation, and strong thermal stability. It is an ideal alternative to traditional ozone-depleting substances such as CFCs and HCFCs;
The core advantage of this material lies in its excellent environmental performance: it has an ODP value of zero, a low GWP value, a short atmospheric lifespan, and does not belong to volatile organic compounds, meeting the requirements of global environmental regulations. At the same time, it possesses excellent dissolving, decontamination, lubrication, and heat transfer capabilities, making it widely used in multiple high-tech and sophisticated fields.
