SBR Rubber vs. PSU
SBR rubber belongs to the thermoset elastomers (rubber) classification, while PSU belongs to the thermoplastics. There are 6 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is SBR rubber and the bottom bar is PSU.
