Thermoplastic PI vs. PMP
Both thermoplastic PI and PMP are thermoplastics. There are 10 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.
For each property being compared, the top bar is thermoplastic PI and the bottom bar is PMP.
