Thermoplastic PI vs. PTFE
Both thermoplastic PI and PTFE are thermoplastics. There are 8 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.
For each property being compared, the top bar is thermoplastic PI and the bottom bar is PTFE.
