PPE vs. Thermoplastic PI

Both PPE and thermoplastic PI are thermoplastics. There are 12 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 PPE and the bottom bar is thermoplastic PI.
