Thermoplastic PI vs. LCP
Both thermoplastic PI and LCP are thermoplastics. There are 13 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.
For each property being compared, the top bar is thermoplastic PI and the bottom bar is LCP.
