AU vs. PEEK
AU belongs to the thermoset elastomers (rubber) classification, while PEEK belongs to the thermoplastics. 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 AU and the bottom bar is PEEK.
