PES vs. C-820 Magnesia Ceramic
PES and C-820 magnesia ceramic belong to fundamentally different material chemistries. PES is a polymeric material, while C-820 magnesia ceramic is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.
For each property being compared, the top bar is PES and the bottom bar is C-820 magnesia ceramic.
