PET vs. SBR Rubber

PET belongs to the thermoplastics classification, while SBR rubber belongs to the thermoset elastomers (rubber). There are 9 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 PET and the bottom bar is SBR rubber.
