PVC-P vs. Limestone
PVC-P and limestone belong to fundamentally different material chemistries. PVC-P is a polymeric material, while limestone is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is PVC-P and the bottom bar is limestone.
