SBR Rubber vs. NBR Rubber
Both SBR rubber and NBR rubber are thermoset elastomers (rubber). There are 10 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
For each property being compared, the top bar is SBR rubber and the bottom bar is NBR rubber.
