PS vs. EPDM Rubber
PS belongs to the thermoplastics classification, while EPDM rubber belongs to the thermoset elastomers (rubber). 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 PS and the bottom bar is EPDM rubber.
