IR Rubber vs. CA
IR rubber belongs to the thermoset elastomers (rubber) classification, while CA belongs to the thermoplastics. There are 12 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is IR rubber and the bottom bar is CA.
