ETFE vs. FFKM
ETFE belongs to the thermoplastics classification, while FFKM belongs to the thermoset elastomers (rubber). There are 6 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.
For each property being compared, the top bar is ETFE and the bottom bar is FFKM.
