PES vs. Sandstone
PES and sandstone belong to fundamentally different material chemistries. PES is a polymeric material, while sandstone is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 14 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.
For each property being compared, the top bar is PES and the bottom bar is sandstone.
