PPA vs. IR Rubber

PPA belongs to the thermoplastics classification, while IR rubber belongs to the thermoset elastomers (rubber). There are 10 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 PPA and the bottom bar is IR rubber.
