NBR Rubber vs. Epoxy
NBR rubber belongs to the thermoset elastomers (rubber) classification, while epoxy belongs to the thermoset plastics. There are 10 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 NBR rubber and the bottom bar is epoxy.
