  R22 is colorless and almost odorless gas at normal temperature and pressure. It is uninflammable, non-explosive and non-corrosive with safety grade to be A1; it can be liquefied as colorless and transparent liquid under pressure. R22 attains high chemical stability and thermal stability, particularly in conditions without water. It shall not react with metal under 200 ℃.
APPLICATION SCOPE
  R22 is a low temperature refrigerant, capable of generating a -80℃ temperature. It is the most widely applied refrigerant in the largest range for the moment. R22 can also be as the raw material for polytetrafluoroethylene resin and intermediate for gaseous extinguishing agent 1211 as well as physical foaming agent for polymer (polymer). Additionally, it can be used as pesticide, aerosol propellants for spray painting and basic material for production of various fluorinated high-molecular compounds.
