Chlorine trifluoride, CF3Cl, is a colorless, nonflammable gas that is widely used in etching and cleaning of metals, scientific research and development, and the production of fluorocarbons. It is also used as a propellant for spacecraft.
When exposed to rubber, chlorine trifluoride can cause a variety of failure modes. The highly reactive nature of the gas can cause the rubber to become brittle and crack over time. Additionally, the gas can cause the rubber to become more permeable to other chemicals, leading to further degradation and failure. Chlorine trifluoride can also cause discoloration of the rubber due to the reaction of the chlorine trifluoride with the rubber's polymer chains.
