PTT vs. Thermoplastic PI
Both PTT and thermoplastic PI are thermoplastics. There are 10 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is PTT and the bottom bar is thermoplastic PI.
