Forsterite vs. PEEK
Forsterite and PEEK belong to fundamentally different material chemistries. Forsterite is a ceramic material, while PEEK is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 6 material properties with values for both materials. Properties with values for just one material (26, in this case) are not shown.
For each property being compared, the top bar is forsterite and the bottom bar is PEEK.
