Thermoset PI vs. DAP
Both thermoset PI and DAP are thermoset plastics. There are 16 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is thermoset PI and the bottom bar is DAP.
