PEEK vs. HNBR Rubber
PEEK belongs to the thermoplastics classification, while HNBR rubber belongs to the thermoset elastomers (rubber). There are 6 material properties with values for both materials. Properties with values for just one material (23, in this case) are not shown.
For each property being compared, the top bar is PEEK and the bottom bar is HNBR rubber.
