PPO vs. CR Rubber
PPO belongs to the thermoplastics classification, while CR rubber belongs to the thermoset elastomers (rubber). There are 8 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.
For each property being compared, the top bar is PPO and the bottom bar is CR rubber.
