Thermoplastic PI vs. POM-C
Both thermoplastic PI and POM-C are thermoplastics. There are 12 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 POM-C.
