ECO Rubber vs. PAI
ECO rubber belongs to the thermoset elastomers (rubber) classification, while PAI belongs to the thermoplastics. There are 11 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 ECO rubber and the bottom bar is PAI.
