Graphite vs. HNBR Rubber
Graphite and HNBR rubber belong to fundamentally different material chemistries. Graphite is a ceramic material, while HNBR rubber is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 5 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is graphite and the bottom bar is HNBR rubber.
