PPO vs. Thermoplastic PI
Both PPO and thermoplastic PI are thermoplastics. There are 9 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 thermoplastic PI.
