COC vs. Epoxy
COC belongs to the thermoplastics classification, while epoxy belongs to the thermoset plastics. There are 12 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 COC and the bottom bar is epoxy.
