Thermoplastic PI vs. PMQ Rubber

Thermoplastic PI belongs to the thermoplastics classification, while PMQ rubber belongs to the thermoset elastomers (rubber). There are 10 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is thermoplastic PI and the bottom bar is PMQ rubber.
