PVC-P and GM-120 glass ceramic belong to fundamentally different material chemistries. PVC-P is a polymeric material, while GM-120 glass ceramic is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 8 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is PVC-P and the bottom bar is GM-120 glass ceramic.
