TUNGSTEN HEXAFLUORIDE Resistant O-Rings and Seals
Tungsten hexafluoride, also known as tungsten fluoride, is a chemical compound used in a variety of industrial applications. It is used primarily as an etchant for metals and semiconductors, as well as an agent for thin film deposition. Other common uses for tungsten hexafluoride include welding and plasma deposition.
When rubber is exposed to tungsten hexafluoride, it can cause the rubber to become brittle and lose its elasticity. The chemical can also cause the rubber to swell and crack, leading to a breakdown of the rubber over time. In addition, tungsten hexafluoride can cause discoloration of the rubber, resulting in an unattractive finish. Long-term exposure to tungsten hexafluoride can lead to the rubber becoming permanently damaged and unusable.
