Epoxy vs. ECO Rubber
Epoxy belongs to the thermoset plastics classification, while ECO rubber belongs to the thermoset elastomers (rubber). There are 12 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is epoxy and the bottom bar is ECO rubber.
