PAR vs. AU
PAR belongs to the thermoplastics classification, while AU 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 PAR and the bottom bar is AU.
