COC vs. Thermoset PI
COC belongs to the thermoplastics classification, while thermoset PI belongs to the thermoset plastics. There are 8 material properties with values for both materials. Properties with values for just one material (22, in this case) are not shown.
For each property being compared, the top bar is COC and the bottom bar is thermoset PI.
