Limestone vs. PES
Limestone and PES belong to fundamentally different material chemistries. Limestone is a ceramic material, while PES is polymeric. 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 limestone and the bottom bar is PES.
