PMQ Rubber vs. Phenolic

PMQ rubber belongs to the thermoset elastomers (rubber) classification, while phenolic belongs to the thermoset plastics. 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 PMQ rubber and the bottom bar is phenolic.
