PETG vs. CR Rubber
PETG belongs to the thermoplastics classification, while CR rubber belongs to the thermoset elastomers (rubber). There are 8 material properties with values for both materials. Properties with values for just one material (24, in this case) are not shown.
For each property being compared, the top bar is PETG and the bottom bar is CR rubber.
