UP vs. Thermoset PI
Both UP and thermoset PI are thermoset plastics. There are 11 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is UP and the bottom bar is thermoset PI.
