PMP vs. SBR Rubber

PMP belongs to the thermoplastics classification, while SBR rubber belongs to the thermoset elastomers (rubber). There are 10 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 PMP and the bottom bar is SBR rubber.
