MIL-0F-017111, also known as Perfluorotributylamine (PFTBA), is an organofluorine compound used mainly as a heat transfer agent and a hydraulic fluid. It is also used in the production of electronic components, as a fire retardant and as an additive in lubricants.
When rubber is exposed to Perfluorotributylamine, it can swell and soften, leading to a decrease in its mechanical strength. The compound can also react with the rubber, leading to the formation of corrosion products. In addition, the rubber can become brittle, resulting in cracking and other structural damage.
