CR Rubber vs. LDPE

CR rubber belongs to the thermoset elastomers (rubber) classification, while LDPE belongs to the thermoplastics. 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 CR rubber and the bottom bar is LDPE.
