EPDM Rubber vs. PS
EPDM rubber belongs to the thermoset elastomers (rubber) classification, while PS belongs to the thermoplastics. There are 11 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is EPDM rubber and the bottom bar is PS.
