FFKM vs. PPS
FFKM belongs to the thermoset elastomers (rubber) classification, while PPS belongs to the thermoplastics. There are 5 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is FFKM and the bottom bar is PPS.
