PCTFE vs. PMQ Rubber

PCTFE belongs to the thermoplastics classification, while PMQ rubber belongs to the thermoset elastomers (rubber). There are 13 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is PCTFE and the bottom bar is PMQ rubber.
