LDPE vs. CR Rubber
LDPE belongs to the thermoplastics classification, while CR 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 LDPE and the bottom bar is CR rubber.
