PPSU vs. CR Rubber

PPSU belongs to the thermoplastics classification, while CR rubber belongs to the thermoset elastomers (rubber). There are 13 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.

For each property being compared, the top bar is PPSU and the bottom bar is CR rubber.
