Phenolic vs. CR Rubber
Phenolic belongs to the thermoset plastics classification, while CR rubber belongs to the thermoset elastomers (rubber). There are 13 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is phenolic and the bottom bar is CR rubber.
