CR Rubber vs. PPSU
CR rubber belongs to the thermoset elastomers (rubber) classification, while PPSU belongs to the thermoplastics. 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 CR rubber and the bottom bar is PPSU.
