PTFE and PCTFE can be used as solid lubricant in cryogenics

Thanks to the particularly exceptional properties of polymers, they are often used as solid lubricants in the field of tribology, especially in cryogenic environments. At atmospheric pressure, cryogenic fluids have very low viscosities. For liquid oxygen, the viscosity is 0.20-10-3Pa-s and for liquid nitrogen it is 0.16-10-3Pa-s [25]. This makes...
