Hexagonal Boron Nitride vs. PTFE
Hexagonal boron nitride and PTFE belong to fundamentally different material chemistries. Hexagonal boron nitride is a ceramic material, while PTFE is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 9 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is hexagonal boron nitride and the bottom bar is PTFE.
