PSU vs. RPU
PSU belongs to the thermoplastics classification, while RPU belongs to the thermoset plastics. There are 9 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.
For each property being compared, the top bar is PSU and the bottom bar is RPU.
