CPVC vs. NBR Rubber

CPVC belongs to the thermoplastics classification, while NBR rubber belongs to the thermoset elastomers (rubber). There are 10 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is CPVC and the bottom bar is NBR rubber.
